Scandinavian Lostbelt

The , designated Order , is one of the seven Lostbelts appearing on the blankened Earth during the Human Order Revision incident. Originating in 1000 BC Scandinavia, its Lost Depth is B+, its King is Scáthach-Skadi, and its associated Crypter is Ophelia Phamrsolone.Fate/Grand Order: Cosmos in the Lostbelt PVFate/Grand Order: Cosmos in the Lostbelt - SIN: Land of Unified Knowledge - Prologue It is the second of the Lostbelts visited by Chaldea Security Organization in the undertaking of the Grand Order to restore Earth and the Human Order.
The events of Chaldea's visit to this Lostbelt are covered in the second chapter of Cosmos in the Lostbelt; Götterdämmerung: , alternatively .
==Setting==
The Lostbelt diverged from the Proper Human History in 1000 BC, during the events of . Surtr, who was supposed to bring the Twilight of the Gods, devoured , gaining his Authority and becoming immensely powerful. He decided to bring about the Twilight of the World, killing many gods and giants before being sealed within a false Sun by Odin. Before dying, Odin then merged the goddess Skadi with Scáthach, creating Scáthach-Skadi, with the purpose of protecting the humans. As Ragnarok was thus interrupted, the world became ravaged by fire and ice, unable to continue past Ragnarok.
Skadi established multiple villages for humans, with the support of the Valkyrie. However, in order to keep the giants at bay, humans are required to reproduce at the age of fifteen or be sacrificed to the giants. Once humans reach the age of twenty-five they are nonetheless forced to be sacrificed. The B+ rank Lost Depth is caused by Earth no longer having humans, with the remainder forced to live in the Realm of Shadows. The Realm itself is only capable of maintaining a few hundred humans before collapsing, and so, the humans are rendered at the bottom of the food chain, essentially kept as livestock.
==History==
=== Prelude ===
The Chaldeans are all shocked that the Wandering Sea still exists. Goredolf Musik calls it the first enigma of the World of Magecraft and the last to be solved. It is an island so mysterious and full of Mystery that not even a gifted mage from a prestigious bloodline like himself could ever step foot on it.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Prologue
Mash, recounting information from Chaldea’s database, explains the Mage’s Association had split into three branches shortly after its inception around the beginning of the A.D. era.
The Clock Tower was founded by the mages who settled in London and focused on developing their Magecraft along with the times. It is the largest and most powerful magecraft organization and the one most synonymous with the Association.
Egypt’s Atlas Institute focused on perfecting their alchemy and have an ironclad rule that their technology must not leave their premises. Chaldea’s first director was granted an exception, though, thanks to the Atlas Contract. Atlas were also the ones who presented him with the Paper Moon.
The Wandering Sea, located somewhere in the North Sea, only recognizes magecraft from the Age of Gods and their ideology is the exact opposite of the Clock Tower’s. This philosophy has made them incompatible with modern human society and why they keep themselves isolated and rarely add to their numbers.
Another reason the Wandering Sea is so enigmatic is that their location keeps moving. They do not move at all rather it is the sea around them that moves. Their island, built before the A.D. era, places Textures onto itself as it moves, essentially making an independent Singularity, and explains how it escaped the bleaching of the Earth.
Goredolf, wishing to be certain, asks Sherlock Holmes if they can trust this distress signal from the Wandering Sea is genuine. Holmes passes it to Leonardo da Vinci, who isn’t sure either, and notes the signal’s wavelength matches the kind Atlas uses. She can verify, though, that there is something at the coordinates provided and recommends going there.
Holmes notes the coordinates lead the seas west of Norway, but regardless if they go through the Scandinavian Peninsula or cut across Denmark, the trip will take a few days since they only just left Moscow.
Da Vinci forbids against using Zero Sail to reach the Wandering Sea for two reasons. First is that the Wandering Sea’s coordinates are in constant flux, making it highly risking to Zero Sail there until they go there directly and establish a connection to it. Second, they lack the energy.
As the current state of the oceans is unknown, Da Vinci recommends they go by land to reach their destination, which means passing through the Lostbelt that covers the Scandinavian Peninsula.
Since it will take two days to reach the peninsula, Goredolf orders everyone to use that time to prepare. He wants Jingle Abel Meuniere to pick any material they come across that could be used to maintain the Shadow Border. He orders Da Vinci to ensure Mash is healthy and for Holmes to come with him to solitary confinement so they may interrogate Kadoc Zemlupus.
Ritsuka demands to go to Kadoc’s interrogation, but Goredolf refuses to let them. Holmes reassures Ritsuka that he’ll see to it the interrogation doesn’t devolve into violence. He also wants to ask Kadoc about the Fantasy Tree and the Sirius Light.
The emergency alarm suddenly goes off; something is approaching the Border’s port side at over 90kmph. An RPG then hits the Border, damaging its composite even though normal weapons shouldn’t be able to.
Holmes orders all staff in the port-side hallway to evacuate to the engine room while he and Mash fend off the attack. He asks Mash to put up a magical barrier in the internal hallway so to fend off a possible second round. Ritsuka tries to go with Holmes and Mash, but Goredolf refuses to let them leave the Command Room.
Meuniere puts up a visual of their attacker and to everyone’s surprise it is Kirei Kotomine chasing after them on foot.
Kadoc wakes up to the sound of a cold and brittle voice and quickly deduces he was taken prisoner. Curiously, his anti-magecraft cuffs are on the floor in pieces. They are cold, suggesting something froze them to the point of brittleness. Kadoc wonders if it was “her” final gift to him.
He finds the Border is under attack and wonders if it’s the Crypters coming to silence him. But refusing to die, he plots his escape.
Another RPG hits the Border, but the damage is minimal thanks to Mash raising her shield in the nick of time. Goredolf notices the NFF marker on Kirei’s rocket launcher, meaning it is one of Koyanskaya’s weapons and explains why it can damage the Border's armor. Everyone then sees Kadoc has escaped to the deck. Goredolf has Ritsuka come with him to stop Kadoc from escaping.
On the deck, Kadoc finds there isn’t any safe way to escape the Border while it’s still on the move. Goredolf, confronting him with Ritsuka, demands Kadoc to return inside the Border, promising to ensure he’ll be treated fairly by international law and the Association. Wanting to keep his promise to live, Kadoc agrees to tell Chaldea everything he knows. Suddenly, though, Kirei appears from behind and seemingly kills Kadoc.
Carrying Kadoc, Kirei explains it was his job to oversee Kadoc’s role as a Crypter. But with that role over, he thought he’d give Kadoc a merciful send-off. He assures Goredolf that eliminating Chaldea isn’t part of his job. As Russia is currently his sole jurisdiction, he had to retrieve Kadoc before they left the region. Without the Alien God’s permission, he cannot move between Lostbelts like Koyanskaya can.
Holmes arrives with Mash and inquires Kirei to tell more about the Alien God. Kirei decides to save his answer for their next meeting and reveals his True Name is Grigori Rasputin, confessing his Spirit Origin is that of a dead man. Holmes, having already deduced all that, asks Rasputin where he came to possess Kirei’s body since he was cremated in the Proper Human History. Rasputin leaves it to Holmes to solve that mystery and that of the bleaching of the Earth and escapes with Kadoc.
Kadoc regains consciousness, feeling as if his heart was stopped. Rasputin confirms it did, explaining to Kadoc Chaldea would have tried to recapture him if Holmes realized he was still alive. He couldn’t let that happen, not after Kirschtaria Wodime asked him to bring him back to Olympus.
Kadoc finds it doesn’t matter if either Chaldea or Kirschtaria kill him. But Rasputin tells him that as he still has the Sirius Light, his life still belongs to the Alien God.

Storm Wall.png
Two days after Rasputin’s attack, Chaldea come across the bizzare remnants of buildings in what used to be Helsinki, Finland’s capital. Investigating, Ritsuka and their allies find signs of survivors. Mash reads a journal with its last entry being two days ago. According to it there were six survivors, but one by one they disappeared, with the journal’s keeper being the last to disappear.
Chaldea soon enters Sweden and reaches the Storm Wall of the Scandinavian Lostbelt. Da Vinci suggests they ignore the Lostbelt until at least after they improve their offensiveness at the Wandering Sea. She then activates Zero Sail so Chaldea may pass through the Storm Wall.
=== Assault of the Demonic Sword (Beginning) ===
Ophelia Phamrsolone recounts how she hated spending Sundays with her parents, even though she didn’t hate her parents and wished to fulfill her family’s long-held dream of reaching the Sixth Imaginary Factor. Her feelings of pride and respect for her parents will never change, so Ophelia asks herself why she hates Sundays.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Section 1: Assault of the Demonic Sword (Beginning)
Meanwhile, in Imaginary Number Space, an unknown entity is trailing after the Border. Holmes finds they cannot discount the possibility that there is another capable of Zero Sailing. It gets closer and Goredolf, not wanting to take any chances, orders an immediate emergency exit into Real Number Space. Da Vinci complies with the director’s order and, with Holmes and Mash’s help, returns the Border to Real Number Space.
Mash is equipped with the Ortenaus and heads out to investigate the Lostbelt with Ritsuka. They immediately find the cold to be a far cry from the frozen hellscape that was the Russian Lostbelt.
Later, reaching the top of a hill, the two observe what appears to be blue flames on the northern mountain range and an abnormally large sun. The Fantasy Tree is also nowhere to be seen, even though it could be seen from outside the Lostbelt. Mash presumes it was camouflaged with magecraft.
Holmes calls Ritsuka and Mash to see how their reconnaissance is progressing. After hearing what they observed, he suspects the abnormally large sun isn’t the actual sun because if it were, the Earth would be scorched. He recalls nothing of the sort in Scandinavian or Germanic folklore but decides to look it up just in case.
As for the flames, he points out that they are actually floating above the mountains. He finds it doubtless that it is the work of magecraft either by the Crypter or a Lostbelt Servant. He then tries to give his deduction of who created the flames when he is interrupted by Fou panicking about a large mask-wearing humanoid approaching Ritsuka and Mash’s position.
As it seems to be speaking some sort of language (though it sounds more like animalistic howling), Mash greets the humanoid in a variety of languages and tries to communicate with it. But it doesn’t understand and attacks.
After it is slain, Holmes states it was a large humanoid native to Scandinavia, one that cannot exist in the 21st century. Mash thus realizes it was a giant, which worries Holmes that creatures from the Age of Gods still live in this Lostbelt. He has updated Chaldea’s database with all he could determine about the giant.
He explains the reason the Border couldn’t detect the giant was because Chaldea had no data on ancient giants. The minute levels of magical energy in the snow and ice creating interference with the Border’s equipment was also a factor. Holmes says he’ll do his best to update their data immediately and sends a firmware update to Ortenaus. With the update, Mash detects several ice beasts approaching with a giant.
After slaying the monsters, Ritsuka and Mash return to the Border. There Holmes deduces the giants they faced were Jotnar, members of the Jotunn race of giants. He explains the Norse world during the Age of Gods consisted of nine realms. Two of these realms, the lands of flame and ice, Muspelheim and Nifelheim, collided and from that Ymir, ancestor to all Norse giants, was born. The Jotnar were spawned from his body. Everyone is surprised by how much Holmes knows on the subject. He confesses though that the information actually comes from when he accessed TRI-HEREMES in Camelot, having perused secret medical data on giants. Even so, he needs more information as he doubts the Lostbelt is merely a world where giants still live.
Mash reminds Holmes that he was going to say something regarding the blue flames when she and Ritsuka were still out on recon. Holmes tries to give his hypothesis on what the flames are when the emergency alert sounds. A figure with a magical reaction rivaling that of Angrboda from the London Singularity suddenly appears.
=== Assault of the Demonic Sword (End) ===
Determining the figure to be a Lostbelt Servant, Ritsuka, Mash, and Holmes prepare to go out and face them when Goredolf suddenly orders an emergency dive. He refuses to let them fight a foe who is both unknown and powerful, and sees diving back into Imaginary Number Space as the only viable option. Fighting is especially out of the question since Ritsuka can’t summon Servants yet.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Section 2: Assault of the Demonic Sword (End)
Da Vinci agrees with Goredolf and starts Zero Sail, only for the Servant to grab the Border at the last second and throw it. The Servant then gets on the deck and starts to easily cut into the Border, despite all of its reinforced armor. Ritsuka, Mash, and Holmes head out to confront them.
On the deck, the heroes confront the Servant――――a masked swordsman. Holmes questions to himself if he truly is a Lostbelt Servant, getting an ominous feeling from his Spirit Origin. The masked swordsman senses neither Mash nor Holmes are pure Heroic Spirits, both having something mixed in. He then attacks the heroes.
During the fight, Holmes questions the masked swordsman on how his demonic sword could so easily cut through the Border’s external armor, which had been reinforced with multilayered Bounded Fields by Da Vinci, Paracelsus, and Nitocris back at Chaldea to be strong as a fortress made of divine iron. The masked swordsman doesn’t answer and continues attacking. Something about him reminds Mash of another Heroic Spirit Chaldea has met. The masked swordsman mentions he has come to steal their prized treasure.
Holmes soon deduces the masked swordsman to be the dragon-slayer Sigurd, one of the most powerful heroes in Norse myth alongside Siegfried. However, that doesn’t explain his monstrous strength nor why his eyes glow red.
Mash notices Sigurd still has yet to swing what she suspects is the demonic sword, Gram. So far he has used only his short swords offensively and Gram to parry the heroes’ attacks.
SIgurd tries to use Gram in response to Mash activating a temporary power-up spell. Holmes tries to stop him, only for SIgurd to sever his right arm. Sigurd is surprised that Heroic Spirts are more fragile than he thought and enters the Border.
Holmes tells Ritsuka and Mash to go after Sigurd without him. He stops Ritsuka from healing him, wanting to them to conserve their magical energy and reassures them that his Spirit Core is still intact. He suspects Sigurd is after something inside the Border. As they cannot let that happen, Holmes empowers Ritsuka and Mash with his Noble Phantasm, Elementary, My Dear, for their upcoming fight against Sigurd.
He estimates Sigurd is a frighteningly unnatural being but as he’s yet full acclimated, there is a chance Ritsuka and Mash can defeat him. Ritsuka and Mash are confused, for which Holmes apologizes he can’t put his thoughts in order in his current condition. Seeing Holmes is generally fine despite the significant loss of magical energy, Ritsuka and Mash go after Sigurd.
Da Vinci tells Holmes that she’ll send someone to get him once she is done evacuating the staff through the rear hatch. Holmes confesses, though, that Sigurd inscribed a Primordial Death Rune into him when he severed his arm, so he can’t push himself or risk his Spirit Core failing. He tries to tell Da Vinci something about Sigurd but he slips into unconsciousness before he can.
Ritsuka and Mash chase Sigurd to the cockpit, only to find it empty. Meanwhile, outside, Goredolf hands the Paper Moon over to Sigurd, who had come for it. Sigurd is surprised Goredolf would give it so willingly as he heard it was their lifeline. Goredolf confirms it is their lifeline, but it is useless when their actual lives are threatened. Without the Paper Moon, they are stranded in the Lostbelt and it’s only a matter of time before they died on their own, so there is no need for Sigurd to kill them. Sigurd agrees to Goredolf’s relief, but that relief quickly turns to despair when Ritsuka and Mash arrive to take the Paper Moon back.
Sigurd, sensing the power boost they received from Holmes, decides RItsuka and Mash are worth killing now. Amused by Mash’s bravado, he asks for her and Ritsuka’s names, having heard it’s what human heroes are supposed to do. Ritsuka and Mash give their names, though Sigurd admits he’ll forget them shortly, which they’re fine with.
He responds to the two’s assuredness of their victory by remarking on how humans will always be arrogant, just like the gods. Mash doesn’t dispute him, but she and Ritsuka refuse to back down. She and Ritsuka then fight Sigurd, confident in their victory.
Powered by Ritsuka’s Command Spell, Mash puts all of her magical energy in a decisive blow to Sigurd. Also, thanks to Holmes’s Noble Phantasm, she is confident it was powerful enough to damage his Spirit Core in several places. But Sigurd shrugs it off and kicks Mash so hard that it damages the Ortenaus’ drive, leaving Mash unable to move. He then swings Gram to behead Ritsuka, but at the last possible moment, his sword stops. His eyes briefly stop glowing red. He decides to let them live and leaves.
In the throne room of a castle made of ice, Sigurd shows his Master, Ophelia, that he retrieved the Paper Moon like she ordered him to. Ophelia tells him to keep it for her and to not let anyone take it, no matter what. With the absence of the Paper Moon rendering the Border useless, she is confident Chaldea can no longer interfere with Kirschtaria.
The queen enters and scolds Ophelia for stealing the Paper Moon, as avarice has no place in her land. She reminds her that every bit of snow and ice covering Scandinavia is a part of her, allowing her to know everything that goes on. Thus, she knows the Chaldeans are currently establishing a Bounded Field to protect themselves from the giants.
Ophelia angrily reminds Sigurd that he was free to kill the Chaldeans, except for Mash. Sigurd responds he can’t tell humans apart, earning more Ophelia’s ire.
The queen questions why the Chaldeans must be killed, to which Ophelia reminds her they are their enemies.
Sigurd offers to kill them all right now. But Ophelia tells him not to, not wanting him to kill Ophelia. Ophelia’s genuine look of concern intrigued the queen since she never batted an eye at that Archer and surmises Mash is very special to her. Ophelia refuses to divulge the nature of their relationship.
The queen forgives Ophelia for her transgression. She then makes it clear to both clear her and SIgurd that she will not tolerate anyone staining her snow, her expression of her love, with blood. She tells them to hold on to love if they ever find it, warning loveless flames will throw everything out of balance if they’re not careful.
In her chambers, Ophelia briefly reflects on love before quickly resolving to not let herself turn out like Kadoc. She declares she will feed on the other Lostbelts and to live up to Kirschtaria’s hopes for her. However, she confesses to Ortlinde, and by extension Hildr and Thrúd through their shared memories, that she is afraid the Lostbelt will not change, even if the Tree is matured, unless she uses the Sirius Light.
=== Lord of Creation (Beginning) ===
The next day, Da Vinci informs everyone that isn’t possible to summon Servants outside of battle in this Lostbelt. While the Border being low on power thanks to the damage it took is a factor, the biggest issue is that Chaldea couldn’t detect any leylines. Da Vinci suspects it’s because of all the magical energy in the snow and ice, which also interferes with long-range comms and may control the Lostbelt’s mana and history. If someone were manipulating the snow and ice via magecraft, they may be the Lostbelt King.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Section 3: Lord of Creation (Beginning)
Moving on to the subject of Ritsuka and Mash’s destination for tomorrow morning, Da Vinci states there is a possible village was detected about 150km from the Border’s current position, given the number of lifeform readings. If so, it will be a good place to gather information and hopefully find allies. Ritsuka and Mash’s mission is to get back the Paper Moon, destroy the Tree, and to find a path to the North Sea.
The next morning, Ritsuka and Mash get ready to leave for their mission, joined by Fou. To make traveling easier, Da Vinci introduces the Ortenaus Ollerus Boards. They are essentially skis equipped with magical energy thrusters, with wards and gyro sensors to help maintain balance. Ritsuka and Mash, and Fou then head out.
As they travel, Ritsuka and Mash notice the trees are made of ice, which worries them that there is no flora. They also come across two ravens flying high above. While Ritsuka and Mash are relieved to see normal animals, Fou is bothered by the birds.
Further into their journey, the heroes hear the scream of a girl being attacked by giants and come to her aid. But the girl tells them that any child being attacked by the Bergrisar (mountain giants) must be abandoned. Ritsuka and Mash refuse to do that and kill the giants.
Amazed by their feats, the girl thinks the Goddess sent them and thanks them for saving her life. She then gives her name as Gerda.
From her ramblings, Ritsuka and Mash learn she came in search of medicinal herbs to bring back to her village for a sick friend. They do not understand why she came without armed adults to protect her, given the obvious dangers.
Gerda admits she had no choice, as the adults are all busy preparing for tomorrow. The envoy’s healing runes can cure any illness, but she will not be coming until tomorrow and Gerda doubts Laura will survive through the night without medicinal herbs. For that reason, Gerda came to this area, where she was told there would be potent medicinal herbs. However, no one is supposed to leave the village, with only the envoys, chosen servants of the gods, being permitted to be outside.
Mash asks Gerda to explain what she means by envoys and gods. But Gerda doesn’t explain, as she assumes Mash is an envoy herself. She also thinks the same of Ritsuka after they offer to help gather herbs.
Mash asks Gerda if she knows about the Fantasy Tree and the sun’s abnormal size. Gerda answers she never heard of any legends about a tree of the size Mash described. As for the sun, she says it has always been that size, like the mountains have always been the way they are. Nobody questions why that is.
Ritsuka and Mash are confused that Gerda never heard of the , given its significance in Norse mythology. However, as Lostbelts are alternate histories different from the Proper Human History, it is possible that the familiar Norse mythology was altered somehow. Mash wonders then if the sun and the mountains are the way they are because of this alternate myth, assuming the myth is historical fact here.
Fou warns everyone of approaching giants. Quietly, they sneak past the giants and reach where the herbs area――――beautiful and warm meadow. However, it also seems to be a haven for giants. Mash recommends they whittle down the giants’ numbers, collect the herbs, then make an emergency escape with the Ollerus Boards. That plan starts earlier than expected, though, thanks to Gerda’s excitement alerting the giants.
As Mash battles the giants, Gerda runs off her own and collects herbs. She is once again amazed by Mash and doubts the giants can ever squash an envoy like her like they do with the adults. Ritsuka tries to ask her what she means by that, but they’re interrupted when Mash has everyone escape.
Koyanskaya visits Ophelia before she heads off to the next Lostbelt after checking on everything and adding to her personal collection. She offers Ophelia her help, but Ophelia vehemently rejects it and demands Koyanskaya that she leave. Koyanskaya recommends they get along, though, claiming they are both human haters. She mockingly reassures Ophelia that she will never have to dread Sundays again.
Ophelia has a momentary flashback of spending Sunday with her parents and seeing the visage of an unknown figure.
Koyanskaya tells her she has nothing to be concerned about anymore beyond dedicating her all to following her beloved’s orders. She calls the Lostbelts, which she says will disappear, a means to pass the time until the Alien God arrives. As such, she wants Ophelia to relax and enjoy her never-ending Wednesday――――Odin’s day.
=== Lord of Creation (End) ===
Ritsuka and Mash arrive at Gerda’s village―――a large walled village with only 50 houses. It is surrounded by a Bounded Field centered on the village gate designed to keep away all beings related to magecraft.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Section 4: Lord of Creation (End)
Mash senses the magical energy that forms the Bounded Field is like the magical energy in the snow and ice, feeling a kindness to it. She agrees with Ritsuka that it is magecraft designed to enrich the lives of people, which may explain why the village is so warm.
Unexpectedly, Goredolf contacts Ritsuka and Mash. It all thanks to the deployment of the Mystic Code drone Da Vinci designed to extend the Border’s comms range.
After hearing Ritsuka and Mash’s report on their current situation, Goredolf decides, given the instability of the connection, that he will remotely interrogate a local himself. But not Gerda, who Goredolf instead asks to get her parents so he may speak with them. It doesn’t work, as Gerda has no concept of parents, nor does she understand what an authority figure is.
Gerda then properly welcomes the Chaldea to her village: Village 23. To repay them for saving her life, she offers Ritsuka and Mash dinner at her house. Ritsuka and Mash find it strange that her village is numbered.
Seeing all the children around, Ritsuka and Mash finally notice a distinct lack of elders. Gerda explains it is because every villager with a 10-year-old child leave when they turn 25 and get eaten by giants. Those who fail to have a child by the time they’re 15 are also sacrificed. Only children and those raising them are allowed to live the hundred villages the Goddess and her envoys made. Gerda doesn’t understand why the Chaldeans are shocked by this.
Meanwhile, Koyanskaya speaks with the queen, thinking she too despises humans. But to her disappointment, the queen actually loves humans and has been keeping their population numbers at 10,000 to prevent their extinction.
The queen considers all creatures in her domain as her beloved children. Thus she will never them let die nor kill them herself. However, sometimes the giants require a sacrifice.
Kirschtaria contacts Ophelia and confirms her concerns about Kadoc were well founded as the Russia Lostbelt has been destroyed. None of the other Crypters know about it. He heard it from Caenis while Ophelia heard from Koyanskaya.
Hinako Akuta has also ceased all communications. Putting that aside, Kirschtaria believes there is no need to inform the others of Russia, as Kadoc’s failure has no impact on their work. Scandinavia Peperoncino’s Lostbelt has an Alter Ego, so he'll learn about it in time. Beryl Gut’s Lostbelt is on the verge of disappearing, so he is busy trying to keep it together.
Kirschtaria tells Ophelia to focus on destroying Chaldea, confident in her Mystic Eye’s ability to harm even Servants. As the Clock Tower no longer exists, she can use her eye as she sees fit. It is no longer that of a shunned child.
Calling the Scandinavia Lostbelt rare and important in part to it an old god still residing there, Kirschtaria believes having a benevolent one such as “her” as an ally would be beneficial if Ophelia can convince her to accept and support their new world.
He then informs Ophelia that Caenis will be visiting. Ophelia asks for his forgiveness if she cannot prevent a clash between Caenis and her Lostbelt King. Kirschtaria finds Ophelia’s confidence in her king and Sigurd’s ability to potentially Caenis to be most encouraging and reaffirms his decision to assign her to Scandinavia. He then ends the call, expecting her next report to be when new seeds have formed.
Sigurd shows himself, amused by Ophelia’s infatuation with Kirschtaria. Ophelia admonitions him for using his spirit form to peep, and reminds him that his duty is to protect her. Sigurd questions if that is even necessary, as the humans in this Lostbelt are harmless and closer to livestock. He recounts how they used to be like those of the Proper Human History: weak beings fit only to be “their” prey.
Ophelia reminds Sigurd that a goddess rules this Lostbelt, which gives it its potential. If they can mature the Tree, they might breathe new life into humanity and nature alike. Ophelia doesn’t care for Sigurd’s contempt for humanity as a result of his origins and temperament, only caring about maturing the Tree. Sigurd reluctantly agrees to ensure the Tree’s growth and goes into spirit form, though Ophelia still feels his gaze.
The Priestess of the Alien God appears, and Ophelia tries speaking with her.
That night in Gerda’s house, Da Vinci contacts RItsuka and Mash. She reviews with them the information they learned about before the connection goes out. Gerda enters at that moment, only seeing a glimpse of Da Vinci’s hologram.
Mash regrets there is nothing she can say to clear up Gerda’s misunderstanding that she and Ritsuka are envoys. Even so, she still wants to ask Gerda something. She goes to speak with her when Goredolf interjects to ask the questions instead, having been listening for the past half-minute.
Goredolf asks Gerda if she ever thought about her future and if she ever wished to be free to see the world without fear of giants. Mash asks her how she can be so cheerful about the fact she will not live past her twenties regardless of her health.
Gerda doesn’t understand why Mash and Goredolf are sad or what they are saying. Mash and Goredolf explain to her that in their world, people live well past 25 and can have many generations of children. Even if they do not have families, some choose to spend their lives with friends and comrades in pursuit of their chosen goals.
Goredolf soon snaps and lashes out that none of the villagers are angry or sad that their lives are doomed to be cut short. Even the Yaga, who had to survive in brutal conditions, were free to live to old age. The connection then starts to act up, so Goredolf goes to bed, very much upset by the whole thing.
The next morning RItsuka and Mash notice the children cheerfully saying their goodbyes to a few adults and handing them bouquets of flowers.
Gerda explains they are special flowers that the children spent six months growing. Without them, you cannot go to Valhalla, for only souls with proof they were loved can go there. The Goddess dictated all of this long ago.
Mash recounts to Ritsuka that Valhalla is meant to be where the souls of chosen heroes gather. It is Odin’s palace, the Hall of Warriors, and only souls chosen by the Valkyries can go ever there. As it is an afterlife, Mash starts to realize what Gerda meant when she said today was special.
At the village gate, Gerda explains to Ritsuka and Mash that it isn’t really meant for entering like they did yesterday. Rather, it is meant only for leaving. It is where the chosen adults go on the ordained day.
The adults perform a ritual to call forth the envoy down from the sky. Soon, a voice from the sky proclaims today is the ordained day, the day they (humans) shall die. It is through this act that the last remaining deity, the Godddess, shows her love for humans. The children pray to the envoy, the Valkyrie, to take the adults to Valhalla.
The envoy descends and commands the adults to sacrifice themselves willingly to the giants once she opens the gate. If they do, their souls will go to Valhalla, even though they are not warriors. The adults are grateful for the Goddess’ love and are ready to walk through the gate.
Ritsuka interrupts the ritual and Mash questions the envoy how she could send those who worship her to their deaths. The envoy moves to kill the pair for resisting the Goddess’ will and aging past fifteen without having children. She declares their souls will not go to Valhalla. Instead, they will be consumed by the giants loveless and alone.
Mash rejects the notion that the ritual is an act of love, rather she finds it cruel for killing children before they can truly grow up. She refuses to watch that happen and readies to fight the envoy with Ritsuka’s support. Gerda pleads with her to stop, as envoys aren’t supposed to fight each other. But Mash confesses she isn’t one and proceeds to fight the envoy.
The envoy is soon felled, but reinforcements quickly arrive. The subsequent battles wear down on Mash.
Gerda implores Mash to stop fighting the envoys, telling her she is perfectly fine with the status quo. Ritsuka and Mash aren’t fine with it, however, as they refuse to let anyone die on their watch.
More envoys appear in the sky, all poised to unleash their Noble Phantasms. But suddenly they are all struck by cannon fire from a man wielding a gigantic cannon. The envoys identify him as a Servant, whom are considered threats to the Goddess’s rule and thus are to be eradicated, not loved. Mash surmises he is a Heroic Spirit from the Proper Human History. The man then joins in fighting the envoys.
The envoys soon realize they will only sustain more losses if they continue and retreat to seek the Goddess’ counsel. After they’re gone, the man properly introduces himself as Napoleon Bonaparte.
=== Castle of Snow and Ice (Beginning) ===
Napoleon immediately has Ritsuka and Mash leave the village with him to an undivulged location. On the way, he explains the Lostbelt is where Ragnarok failed to end the Norse Age of Gods. For the past 3000 years, affairs have remained as they were in 1000 B.C. when the Age of Gods was meant to end.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Section 5: Castle of Snow and Ice (Beginning)
He reveals the Goddess is an actual god, having survived Ragnarok and never turned into a Divine Spirit. She is the Lostbelt King, using her envoys to keep as a go between to keep the giants and humans in check. She lives in a castle in the northern part of Oslo Fjord. Her name is Scáthach-Skadi―――Goddess of Snow and Ice. Napoleon suspects her castle is where the Crypter, Sigurd, the Paper Moon, and the Tree are.
Meanwhile, the queen explains to Ophelia that while she can command the giants to do whatever, she cannot suppress their instincts. Giants consume heat in all its forms and will awaken from hibernation at the slightest hint of a new heat source and devour it immediately. Ophelia therefore concludes they cannot serve as a proper disciplined army like she suspected.
The queen agrees with Sigurd that the giants are third rate as familiars, being shadows of their former selves. But they once proud souls and so she loves them like all living in Scandinavia. The “flames” twisted them into the walking calamities they are today, so she will keep them in check. With the masks she made, she will reunite them under her rule, for she is a descendant of Ymir.
Napoleon explains Scáthach-Skadi is a fusion of the Norse goddess Skadi and the Celtic Warrior Scáthach. Mash recalls hearing certain aspects of Scáthach from Proper Human History may have blended in with Skadi, and deduces Skadi is the predominant figure in this Lostbelt. Napoleon confirms that is indeed the case.
He then recalls hearing Skadi loves all forms of life, which means they reason with her so long as they do not make enemies of her. Mash fears they already are since they destroyed a number of envoys. Napoleon assures her it will take more than that to anger the self-proclaimed mother of Scandinavia.
Finding his knowledge of Scandinavia peculiar since none of his exploits in life pertain to it, Mash deduces Napoleon’s knowledge was acquired after he materialized. Napoleon confesses he materialized a little before Chaldea arrived, allowing him to get information as he traveled the land. He decides not to divulge the source of his information for the moment, however.
Mash asks Napoleon if it’s true another envoy will not come to Village 23 for another year, like Gerda said. Napoleon confirms from personal experience that is indeed the case. As envoys are forbidden from sacrificing humans on any day besides the ordained day, Napoleon surmises the reason so many came to Village 23 was to ensure the ritual wasn’t disrupted again.
He confesses that back at another village he shot an envoy just as she was about to open the gate. There was only one envoy there, though, as disrupting the ritual was unthinkable. But when Napoleon shot her down, she shared that experience with the rest. In response, the envoys shored up their numbers in preparation for another attack. Though they are powerful, they are merely mass-produced dolls Skadi made based on the valkyrie sisters.
Enemies soon approach. As they’re still far off, Mash considers using her thrusters to make a clean getaway. But Napoleon wants the enemies to find them, so he may have a better look at how RItsuka and Mash fight. He wants to hone their skills as a unit. Ritsuka agrees and the heroes proceed to fight the enemies once they’re spotted.
Meanwhile, Skadi, finding the others incompatible, decides to cooperate with the Greek Lostbelt like Ophelia originally proposed.
Moving onto the topic of the incident at Village 23, Skadi informs Ophelia that the Chaldeans joined forces with “that man” and destroyed a number of envoys. Ophelia and Sigurd are ready to find and kill them at her word. Skadi reminds them they are forbidden from killing. However, she has no issue if the heroes are killed by the giants or the envoys, finding that to be natural. She will kill them herself if they are enemies or love them as her own children if they are not like she does with every creature in Scandinavia.
She then summons Thrúd and asks for her analysis of the incident at Village 23. Thrúd, based on her the valkyries’ shared records, finds there is no need for her and her sisters to respond. Even if the heroes end up as their enemies, she believes giants or a self-destructing envoy will be sufficient enough to kill them.
Sigurd, irritated by the valkyrie’s boasting, urges Ophelia to order him to kill Thrúd. Intrigued, Skadi challenges Sigurd to test his demonic sword against Thrúd, who is more than willing to kill Sigurd if the queen so commands. But Skadi confesses she was only joking to Ophelia’s displeasure. She then returns to her throne, suspecting the heroes will arrive by tomorrow evening if they survive the journey.
The heroes finish eliminating the last of the enemies. Napoleon, after giving Ritsuka and Mash tips on fighting gainst, sees it’s about to be nightfall. So he takes the pair to one of the camps he had set up throughout the Lostbelt using supplies he “borrowed” from that village.
After eating, the heroes discuss their plan for tomorrow: infiltrate Skadi’s castle with the goal of retrieving the Paper Moon and acquiring information about the Tree. Because she doesn’t see them as enemies, Napoleon believes Skadi’s guard will be down and explains what they’ll do once they’re in her castle.
=== Castle of Snow and Ice (End) ===
Setting out the next morning, Ritsuka and Mash see the ravens again. Napoleon claims they led him to RItsuka and Mash before saying he is joking. The heroes then travel to Skadi's castle.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Section 6: Castle of Snow and Ice (End)
The heroes enter the castle through the back. Napoleon confesses like RItsuka and Mash that he once tried to breaking in before. While he ultimately failed, he did learn a few things. One being the underground passage they're currently using leads to the main building. The main bridge is too heavily fortified with envoys to use, so the underground passage is the safer option.
Napoleon notices Skadi didn’t increase security from last time, meaning he isn’t seen as an enemy, and surmises she is already aware of their presence. The heroes then encounter ice beasts who have made the tunnel their home and slay them.
Exiting the tunnel, the heroes make their way to the throne room, where Ritsuka and Mash finally meet Skadi. She is already aware of everything they have done, for which she’ll forgive as she loves them as her children. She also commends them for surviving their first encounter with Sigurd.
Ritsuka and Mash sense true affection from Skadi’s words, and so they feel they can reason with her. But Mash notes how her magical energy permeates the entire castle and is so crushingly intense that is comparable to that of the Seventh Singularity.
Skadi recognizes Napoleon, though his name escapes. Napoleon explains who he is as he did before, but Skadi has no interest in the names or deed of those from Proper Human History.
Because she has decided to love them, she will not kill the heroes. Even so, she will not divulge to them the location of the Tree, knowing they intend to destroy it, and that would be an unforgivable sin. They are free to take the Paper Moon, though its current owners may be against it.
Skadi orders Thrúd to capture the heroes. Napoleon identifies Thrúd as one of the original valkyries the envoys are modeled off of, and reveals she and her sisters command that army.
Thrúd request Skadi’s permission to use a Muspel to make easier to capture, which Skadi grants. A hole then opens in the floor and out of it comes a Muspel. Thrúd establishes a quasi-link with the fire giant and moves to capture the heroes.
The heroes defeat the Muspel and continue fighting Thrúd when Sigurd and Ophelia show themselves. At Ophelia’s request, Skadi orders Thrúd to stand down.
Mash tells Ophelia that she has grown and learned so much in the two years they last spoke. Now she wants to know if there was any meaning to the time she spent with Team A. Though she is proud to see how much Mash has grown, Ophelia regrets they cannot speak like she always wanted to as she cannot shirk her duties as a Crypter, meaning they are enemies. Despite that, Mash feels they both want to settle things peacefully.
Napoleon interrupts Ophelia before she can reply. He reveals he met Ophelia when he first broke into the castle and claims she is his fiancee. Ophelia absolutely denies she is and goes on a rant about how such cultural norms are meaningless in the current world. She found Napoleon’s proposal to be so absurd that she didn’t even respond, though Napoleon took it to mean yes.
Ophelia quickly loses her patience at Napoleon’s declarations of his love for her to the point she requests Skadi's permission to kill him. Skadi refuses to grant it and instead orders Ophelia to capture him. So Ophelia orders Sigurd to neutralize the heroes without killing, especially Mash. Sigurd gets ready for battle; Mash is unnerved that she can sense his magical energy even with the castle so saturated with Skadi’s.
As the battle goes on, Sigurd becomes impressed with the heroes and requests Ophelia to remove one of his limiters. Ophelia grants his request, and Sigurd goes undergoes Ascension. Yet, despite the obvious difference in power, Mash refuses to give up. Ophelia is amazed by the person Mash has become and regretfully uses her Mystic Eye to reverse the Ortenaus’ output. Yet even with the exoskeleton now weighing down on her, Mash continues to fight Sigurd with her companions.
Skadi orders the battle to stop, having noticed Mash is struggling to even breathe. Ophelia and Sigurd comply. Skadi then immobilizes the heroes with a Primordial Rune when Caenis appears.
Ophelia explains Caenis is a Lostbelt Servant contracted with Kirschtaria with the Authority to cross between Lostbelts to inspect them. She reminds Caenis, who is eager to kill, that she still isn’t permitted to fight and that her power is meant to help Kirschtaria realize his ideals. Caenis rejects that Kirschtaria’s goals are related to his ideals, believing he is just vindictive and so ambitious that she isn’t ashamed she lost to him.
Impressed that they killed Ivan the Terrible, Caenis decides she will kill Ritsuka. Incredibly, despite being immobilized by a Primordial Rune, Napoleon aims and fires his cannon at Caenis. Caenis blocks the shot with her hand and moves to kill Napoleon. Sigurd stops her in accordance with Skadi’s decree that killing is prohibited. Caenis argues with him for a bit when she notices something about him that piques her interest.
She then delivers a recorded message from Kirschtaria to Skadi with the assumption Chaldea would be there given its close proximity to Russia.
Kirschtaria explains the Crypters’ goal is to rewrite human history with the Alien God’s help and to establish a new Age of Gods. He reveals the Fantasy Tree of his Lostbelt, Greece, is already fully grown and has been dubbed Atlas by Zeus. Its roots cover 80% of the planet’s surface. So long as it remains, Chaldea can never restore the Proper Human History even if they destroy the other Lostbelts. Kirschtaria then ends the message, imploring Skadi to join him in establishing a new Age of Gods.
Skadi seems intrigued with Kirschtaria’s proposal. Caenis threatens to kill her when she nearly brings up Poseidon’s rape of her. But not wanting to betray Kirschtaria’s trust, she reluctantly backs down.
Ophelia demands Casenis return straight to Kirschtaria. having heard a number of Heroic Spirits from the Proper Human History are appearing in the ocean now that Poseidon is gone. Caenis agrees, needing to check in on Artemis as well. She leaves, telling the Chaldeans to become halfway decent warriors for when they next meet.
=== The Other Goddess (Beginning) ===
Like they planned from the start, the heroes are now prisoners in the castle dungeon. There Ritsuka and Napoleon forge a temporary contract. Napoleon then starts talking about their next step when Ritsuka drifts into unconsciousness.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Section 7: The Other Goddess (Beginning)
In the dream, a figure with a familiar voice surmises Ritsuka fell into it when someone took advantage of a flaw in their temporary contract to form a connection with him. He then helps Ritsuka in getting back their soul and sense of self and to meet with the one who invited them.
Ritsuka soon locates the one who invited them into the dream, but first they must the gigantic guardian barring their way. After they do, a girl’s voice commends Berserker for protecting her and relieves him of his duty.
Berserker disappears and Ritsuka’s companion confirms the voice they heard belongs to the one who invited them. He also confirms Ritsuka’s soul and sense of self returned when Berserker was defeated. He himself then disappears, as RItsuka needs to continue alone.
The girl confesses to Ritsuka she forcibly bonded with them while they were in process of contracting with Napoleon, which is why they fell into that dream. She says she is someone with a deep connection to the Holy Grail, though she is only a small fragment of that person. She is Alter Ego Sitonai. 
=== The Other Goddess (End) ===
Ritsuka wakes up and sees Sitonai is in the cell. Mash tells Ritsuka that she just suddenly appeared after they collapsed. Sitonai confirms she was a prisoner before the heroes were.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Section 8: The Other Goddess (End)
She reveals she is a Pseudo-Servant, with Illyasviel von Einzbern as her vessel. She is also a High-Servant, boasting that she is composed of three goddesses.
She assures the heroes that she is a Servant from the Proper Human History, as Illya is connected to the Grail and the Einzberns do not exist in the Lostbetls. She materialized around the time Napoleon did. It wasn’t long, though, before she became Skadi’s prisoner. As for why she wasn't killed, Sitonai posits it’s because Skadi is her stepmother through one of her goddess components: Freyja.
Mash disagrees, considering that this Skadi is a complete divergence from herself in Proper Human History. Sitonai concurs, as that is what Freyja is telling her. But considering Ophelia taught her about the Proper Human History’s Norse mythology, it’s possible Skadi didn’t kill Sitonai because she was fused with Freyja, the daughter she could have had.
Sitonai confesses she knows a lot about the castle and its residents, thanks to using Louhi’s dream walking. Asked about SIgurd, she reveals his Spirit Origin at least comes from the Proper Human History. Mash is incredulous that Sigurd isn’t a Lostbelt Servant as his magical energy clearly wasn’t that of a Servant from the Proper Human History.
Sigurd has the Paper Moon. He also follows Ophelia, who obviously knows the Tree’s locations, everywhere. The heroes must therefore first defeat him to achieve either of their objectives. Sitonai reveals there is something Ophelia and Sigurd sealed away that would of great aid in their battle against him.
Mash contemplates following Chaldea’s original plan to ignore the Tree until after they reached the Wandering Sea. Sitonai warns the Tree will only continue to grow unless it is destroyed as soon as possible. The bigger it gets, the more rooted it becomes, making that much harder to destroy. Ritsuka and Mash agree to talk with the Border crew first.
Sitonai reveals the heroes’ trump card against Sigurd is a goddess from the Proper Human History summoned as part of humanity’s last attempt at resistance. Then, after giving the goddess’ location, she opens the cell door, and conceals the heroes so they can escape.
The Heroes make it outside, where they would have been ambushed by Koyanskaya if not for Fou’s warning. Koyanskaya sics the giants she had been hiding under the bridge on the heroes. They breakthrough the giants and escape.
=== Like the Spring Sunshine (Beginning) ===
Ophelia reports to Skadi that the heroes escape. She also suspects Sitonai told them about the goddess imprisoned in Mt. Hindarfjall No. 2. She requests permission for her and Sigurd to recapture the heroes.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Section 9: Like the Spring Sunshine (Beginning)
Skadi denies her request as she has already decided to love the heroes as her children. She knows Sigurd would rather kill them, with the Scáthach in her informing her that he cannot be easily used. She tells Ophelia to use this time to reflect on herself and to give some thought to Mash and Napoleon.
In her room, Ophelia regrets she didn’t visit the heroes because Napoleon irritates her and worriers if she’ll ever get to talk with Mash again. Koyanskaya enters and starts admonishing Ophelia for being in love with Kirschtaria, yet unable to fully commit to both his cause or her own feelings. She surmises it is because Ophelia cannot be honest with herself about the fact she never truly trusted anyone. She also mocks her for still having her childhood anxieties.
Ophelia demands Koyanskaya to leave immediately and threatens to have Sigurd kill her if she isn’t gone by the time she is back. She then goes out onto the terrace for some fresh air.
Koyanskaya ponders if she went too far in motivating Ophelia. Sigurd threatens to kill her if she takes her “playing” with Ophelia too far. Koyanskaya dismisses his threat and addresses him as “Your Majesty”. She claims she treats her customers with nothing less than the utmost respect. She is counting on Ophelia to help unveil the Lostbelt’s true nature.
The heroes reach , where the third goddess is imprisoned. At its peak, they find an ice castle surrounded by magical flames acting as a barrier. Mash thinks it is the Palace of Fire from the poem “” and the . It is Bounded Field created by Odin himself.
Mash thinks it has existed since the Age of God. But Napoleon surmises it is only an imitation and points out the Muspel walking in the flames with their legs in chains. Presuming the giants guard the castle, the heroes proceed to slay them.
Though they slew the giants, the flames do not reseed, nor do the castle doors open like the heroes hoped. As they contemplate how to bypass the flames, the remaining Muspel approach them when an unknown lifeform crashes down and attacks them.
The heroes slay the giants, and Napoleon shoots the lifeform with such force that it crashes into the castle. It is then thrown back and destroyed by the castle’s occupant. She is the daughter of Odin, last of the Valkyries, and lover of Sigurd in life―――Brynhildr. 
===Like the Spring Sunshine (Middle)===
Outside the castle, the Valkyries gather, having sensed that their sister from Proper Human History has awoken. They hoped she would stay asleep, but now they must stop her from joining the humans of Proper Human History.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Section 10: Like the Spring Sunshine (Middle)
Brynhildr vows to help the heroes restore human history, feeling there is someone in the Lostbelt she is meant to fight.
Napoleon flirts with her, even though he has already proposed to Ophelia. He tries to excuse his womanizing by saying he only professes his true love for someone once per materialization, but the others aren’t hearing it.
Brynhildr casts a rune of illusion on Napoleon to make him think a pile of snow is her reciprocating his feelings. He tries to embrace the snow and ends up facedown in it. Napoleon should be resilient to this sort of magecraft as an Archer, but his Magic Resistance can’t help against Primordial Runes.
Ritsuka and Mash tell Brynhildr why they sought her, leading her to conclude Sigurd is in the Lostbelt and to realize why she was summoned.
She recalls how she wandered the Lostbelt when she first materialized, not understanding why she was summoned. Eventually, she was sealed away by her sisters and Ophelia and put to sleep in that imitation Palace of Fire.
Though she understands her purpose to kill Sigurd, Brynhildr seems to hope he isn’t the one she knows. Napoleon, recovering from the illusion, disagrees, inclined to agree with Sitonai that Sigurd isn’t from this Lostbelt. He reminds Brynhildr that Skadi has had this Lostbelt’s humanity in lockdown for 3000 years. As such, there is nothing in the way of desire to turn someone into a Fafnir for Sigurd to slay. Even if a Sigurd was born in this Lostbelt, without an evil dragon for him to slay, he could never become a hero. Brynhildr realizes it is a world without heroes.
With Brynhildr recruited and Mash’s armor in probable need of maintenance, the heroes decide now is a good time to return to the Border and head for Norrkoping near where it is parked. On their way, though, Napoleon wants to make a stop to gather information. He also figured it was time to take a break since it was getting close to sunset.
The heroes stop at Village 67, which Napoleon is familiar with. Asking around, he determines it is safe for them to rest, as there are no giants or envoys in the area. Brynhildr discovers that the village’s Bounded Field was strengthened, but not with runes.
Suddenly, Ritsuka and Mash are reconnected to the Border. Before the connection goes out, Goredolf warns them that giants are approaching Village 23 and orders them to protect. The heroes immediately set out to save Village 23.
They reach the village by nightfall to find it safe, learning from Gerda that someone claiming to be from Chaldea possibly saved it.
After supper at Gerda’s house, Brynhildr informs Ritsuka and Mash that the village’s Bounded Field was indeed reinforced in the same way Village 67’s was. Napoleon also informs them giants came to the village because of a tear in the old Bounded Field, which he surmises was caused by their fight with the envoys.
Mash confesses she and Ritsuka tried several times to contact the Border, to no avail. She cannot understand when it seems impossible to connect now when it wasn’t before and wonders if the new Bounded Field is why.
Suddenly, the heroes hear giant footsteps and go out to deal with it. They see several giants trying to find the tear they do not know was repaired and go slay them.
Afterward, Gerda comes out and tells Mash that she has come to realize that neither she nor Ritsuka are envoys and apologizes for being wrong. Even so, she still thinks highly of Mash and remains grateful to her. Mash can only reply with a sad “you’re welcome”. 
===Like the Spring Sunshine (End)===
The next morning, Ritsuka and Mash are contacted by Da Vinci, who made adjustments to improve the connection. Immediately, she tells them the Border is under attack from flying humanoids, envoys, thanks to Goredolf driving it out of the Bounded Field to try to get a better signal once the vehicle was repaired. The heroes are sent the Border’s coordinates and immediately set out to save them.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Section 11: Like the Spring Sunshine (End)
Breaking through the giants in their way, the heroes eventually catch up to the Border and jump onto its deck.
Brynhildr mourns that the envoys are nothing more than soulless automata. She introduces herself to them and implores them to leave, not wishing to harm them. The envoys cannot comprehend that Brynhildr exists as they were only ordered to destroy the Border, so they request additional orders from the commander units.
After she destroys a number of envoys, Brynhildr tries again to implore them to leave. Thrúd’s voice challenges her sister and Chaldea to go up against a hundred envoy simultaneously. Da Vinci, however, has lured in the giants from earlier and they attack the envoys as they are the largest heat source. With the envoys’ attention primarily away from them, the heroes set out to find Thrúd.
Brynhildr soon located Thrúd, along with Hildr and Ortlinde. She calls out to them and demands they come down and face her. They come down after Thrúd asks Brynhildr why she has sided with the humans.
Thrúd tells Brynhildr that they do not truly considered her to be their sister as she is from the Proper Human History and therefore did not experience the broken Ragnarok. She and Hildr recount how Ragnarok was meant to be, only for it to go completely wrong.
Ortlinde confesses to Brynhildr that they were all happy when they met her as they hoped she would join them since she is from a world without their broken Ragnarok. Brynhildr replies she can never do as she was summoned to restore humanity.
The Valkyries all tell Brynhildr that is why they put her to sleep because, if she remained so, they could have avoided fighting like they all wanted. Everything about her reminds them of their Brynhildr, so they thought it was the same for her. Hildr asks her then if they are nothing more than strangers to her and that is why she has no issue killing. Brynhildr is taken aback. Napoleon takes over the conversation for her.
Thrúd tells Napoleon he wouldn’t understand how it feels to have their eons-long dream of seeing their sister, whom they thought dead, again. Napoleon counters that Brynhildr doesn’t want to kill them or anyone, but warriors must carry the burden of the lives they take.
Brynhildr concurs with Napoleon and believes her sisters have forgotten that after so many years in a world bereft of heroes. If they have forgotten true heroes are born in battle, they are not fit to call themselves Valkyries, for they can no longer carry the souls of brave heroes. The Valkyries take offense to their sister’s words and fight her to prove they are true Valkyries.
As they battle, Brynhildr is glad to see her sisters have developed emotions like she has. Thrúd and Hildr both deny it. Thrúd flies into a rage, believing Brynhildr’s affections for Sigurd have corrupted her mind. Her magical energy raises; Ortlinde begs her to calm down as she is leaking magical energy. Hildr also flies into a rage and attacks Brynhildr with Thrúd.
In the battle’s last moments, ashamed they truly did develop emotions, Thrúd and Hidlr impale themselves on Brynhildr’s spear. Thrúd tells Ortlinde that she cannot join them in death, suspecting their decision shocks her because she isn’t as broken as them. Hildr tells her to follow her heart, believing she gained one like they did. After her sisters disappear, Ortlinde retreats, unable to understand their final decision.
===You, Who Was Like The Spring Sunshine===
Peperoncino calls Ophelia, expressing concern for her. Ophelia denies that anything’s wrong, though she appreciates Peperoncino calling her. Peperoncino also thinks Sigurd isn’t good for her health. Ophelia doesn’t let Peperoncnino know Sigurd is why she is worried.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Section 12: You, Who Was Like The Spring Sunshine
Ophelia’s Tree impresses Peperoncino, seeing that is already sprouting seeds. Ophelia says it is only thanks to the Lostbelt’s rich soil and regrets the seeds withered away. She wishes she could keep a simple so she can report something to Kirschtaria. But Peperoncino calls the fact the Tree is sprouting seeds proof of its growth and Ophelia’s positive relationship with the Lostbelt King. He tells Ophelia to apply a little makeup, knowing she wishes to look her best for Kirschtaria, which Ophelia admits to.
Peperoncino confesses he’s been trying to get contact Kadoc, though Kadoc seems to be refusing to answer his calls. But given the fact that Chaldea arrived in Russia, he can deduce what happened.
After Peperoncino ends the call, Ophelia laments Brynhildr is free. The Priestess appears. Ophelia wonders if she has come to scold her for not killing Brynhildr when she had the chance. She tried to do it but she couldn't bring herself to do it because she knew Brynhildr died in life when her love went unrequited, She certainly couldn't do it using the demonic sword of her beloved. Skadi then decided to love Brynhildr, so she had to be kept alive.
The Priestess leaves. Sigurd leaves spirit form and asks Ophelia if she was talking to herself again, completely unaware of the Priestess. He then informs Ophelia that Thrúd and Hildr were killed, so it’s only a matter of time before Brynhildr and Chaldea return to the castle. Eager for their arrival, he puts it in terms Ophelia can understand: “Sunday is close at hand. Ahh, what a feeling.”
In the throne room, Ophelia begs for Mash to stay away from the castle and quietly calls out to Kirschtaria.
Ortlinde returns and reports that her sisters and fifty envoys died in battle against Brynhildr and Chaldea. She denies that she’s crying, unable to believe her sisters choose to fight just to die. She knows she should be proud they died a warrior’s death, yet her tears will not stop. Because she is somewhat broken herself, she can understand her sisters’ final decision was made out of love for their elder sister.
Now understanding the danger the Fantasy Trees pose thanks to the heroes’ conversation with Sitonai in Ritsuka’s report, Goredolf makes destroying the Tree a top priority. But before that, they must first defeat Sigurd and negotiate with Skadi. The biggest concern, though, is Ophelia’s Mystic Eye, which Brynhildr believes she can do something about. Chaldea’s goal is to get back the Paper Moon and learn the Tree’s location, which they can learn from either Ophelia after capturing her or Skadi. Ophelia may be suspectible to negotiating once Sigurd is defeated.
Driving toward Skadi's castle, the Border stops at Torsby for the night since driving at night is too dangerous. RItsuka goes up on the deck and is joined by Brynhildr. She describes to them the nature of her Noble Phantasm and tells them about her past.
Because the version of her inscribed in the Throne is based on the moment she killed Sigurd while wreathed in madness, Brynhildr believes that is why she can kill him even though she loves him and why she could kill her sisters. Even so, she doesn’t want to be believe the SIgurd in this Lostbelt is cruel, as the Sigurd she loved was a good man. For that, she thanks Ritsuka for not treating her like a tool soley for killing Sigurd. Fou then suddenly comes up, so Brynhildr ends her conversation with Ritsuka and has them rest for the battle tomorrow.
The heroes arrive at Skadi’s castle at noon the next day. They charge ahead when Muspel and ice beasts come up from beneath the bridge. The party promptly slay them. 
Sigurd appears from the other side of the bridge and challenges Brynhildr to combat. Brynhildr readies to fight him, accepting that he has sided against humanity, when Ortlinde. She tells Ortlinde to stand down, but Ortlinde refuses and takes up her spear for the same reason her sisters did. She then overloads her magical energy and synchronizes it with Gram’s so she may fight alongside SIgurd. Sigurd is amused by this and fights the heroes.
Brynhildr realizes Sigurd is stronger than she thought, so she activates the Odinseal, a Primordial Rune that will empower her at risk of burning her soul away. With the activation of the Odinseal, Sigurd is no longer amused and decides to kill eveyone. But Ophelia arrives and reminds him he is only supposed to kill the Servants.
She asks Mash why she has come. Mash answers it is because of her duty, though she admits she hasn’t met enough humans to feel any obligation toward them. But even if they destroy the Lostbelt as a result, she and Ritsuka have resolved to see their world restore no matter what.
Ophelia admires Mas’s strength to continue, despite the guilt weighing down on her. She accepts she can never be like her, but even so, she refuses to betray Kirschtaria’s faith in her.
She uses her Mystic Eye to undo the benefits of the Odinseal, but not the damage being done to Brynhildr’s Spirit Core. But she refuses to give up and has deduced Ophelia’s Mystic Eye isn’t truly reversing phenomena, rather it determines their possibilities.
Despite the risks, Brynhildr reactivates the Odinseal. Her fixation on killing Sigurd also renders Ophelia’s Mystic Eye meaningless by narrowing all possibilities into a single path. She then uses Brynhildr Romantia to kill Sigurd, but it does not work, even though it was created for him.
Sigurd reveals he isn’t Sigurd. He demands Ophelia quickly release his second limiter, feeling that his Spirit Origin is at its limit. Ophelia refuses to let that happen and releases Sigurd’s final limiter, ascending him to his fullest capabilities.
Surtr breaking seal.png|Surtr breaking from his seal.
Surtr.png|Surtr
With a swing of his sword, Sigurd attacks the heroes with flame. Brynhildr truly realizes he isn’t Sigurd, as the real Sigurd absolutely refused to use fire runes. “Sigurd” tells Brynhildr she would know what this fire in his soul means if she were a god and attacks the heroes.
Brynhildr cleaves his Spirit Core, but “Sigurd” still isn’t dead. He reveals he was waiting for someone capable of piercing Sigurd’s Spirit Core, as the Command Spells had forbade him from committing suicide. Ophelia tries to use her Mystic Eye to undo his defeat, but “Sigurd” uses the method Brynhildr had used earlier.
Ophelia panics and warns “he” will arrive after “he” breaks Sigurd, his shell. She cannot stop “him”, confessing Kirschtaria had entrusted “him” to her. Screaming, she points at the false sun and can only watch in terror as Surtr, Fiery King of Giants, frees himself.
===Bringing Twilight Here Once Again (Beginning)===
In an inner monologue, Ophelia confesses she hated Sundays because she hated herself. She detested her weakness and how her parents’ wishes made her feel trapped. Not once did she ever think about running away, which is why she wished for someone to come and save her and tell her she doesn’t have to do anything.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Section 13: Bringing Twilight Here Once Again (Beginning)
The moment the false sun fell, the masks created by Skadi to pacify the giants all shatter. Their roars echo throughout the land as they pray to their king to let Ragnarok recommence in a language incomprehensible to humans.
Holmes has recovered enough to walk about. Seeing Surtr, he regrets he was too late and reveals the flames at the northern mountains fell from Muspelheim―――—the false sun, the body of Surtr himself.
Ophelia recalls, after Team A was killed by Lev Lainur’s sabotage, seeing with her Mystic Eye that the Alien God initially only wanted Kirschtaria. But Kirschtaria convinced it to resurrect the rest of Team A as well and agreed to pay the price for their resurrection.
The moment the Alien God resurrected her, Ophelia saw the Lostbelt through her Mystic Eye and met Surtr for the first time. Surtr proudly admitted he tried going against fate by destroying the world instead of just ending the Norse Age of Gods. He failed and was imprisoned by Odin to await the pruning of his world. Ophelia felt sympathy for Surtr as she and Team A also failed, though their objectives were opposite to his. She and Surtr then said their goodbyes, with Surtr promising to show her the end of the planet should they ever meet again.
At the very first meeting of the Crypters. Ophelia was baffled that none but herself knew of the price Kirschtaria paid to resurrect all of them. When she confronted him about it afterward, Kirschtaria confessed he said nothing because he wanted everyone to give their absolute best without gratitude weighing them down. He then assigned Ophelia her to the Scandinavia Lostbelt with the warning to be careful when she summons her Servant there, as destruction factors heavily in Norse Mythology.
In Skadi’s throne room, Ophelia summoned Sigurd without a Catalyst, believing it was thanks to her mother’s nordic bloodline. She thought Sigurd was a Lostbelt Servant, but “Sigurd” corrected her that his body isn’t from the Lostbelt. But reminded of when they first saw each other, she realized “Sigurd” was, in fact, Surtr. Surtr explained his soul linked with her Mystic Eye in that moment, allowing him to infiltrate her summoning of Sigurd and possess him.
He demanded that Ophelia use her Command Spells to destroy Sigurd’s body, so his own soul can be set free. Once freed, he will destroy the false sun that is imprisoning his true body from its vulnerable outside. Wishing to prevent the destruction that his resurrection would bring, Ophelia used her Command Spells to forbid “Sigurd” from killing or harming himself. Afterward, she reported on Surtr to Kirschtaria, who saw Surtr as a powerful asset for their cause so long as he is controlled.
The heroes defend themselves from Surtr’s onslaught, only surviving his heat thanks to the magical energy in the snow and ice. Holmes warns them of Surtr’s Noble Phantasm, his flaming sword, is a Divine Construct born from the planet that prioritizes lifeforms above all else, including gods.
Surtr unleashes his Noble Phantasm. Sigurd, still alive, watches as Mash defends herself and Ritsuka against it with her man-made shield. Inspired by her bravery, he makes a stand to atone for what was done with his body and unleashes Bölverk Gram.
===Bringing Twilight Here Once Again (Middle)===
With Ophelia on his shoulder, Surtr heads for the northern mountain where the Tree is. Ophelia tries calling Kirschtaria, but Surtr’s magical energy is blocking the signal. The Priestess appears, and like before, Ophelia cannot understand what she is saying.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Section 14: Bringing Twilight Here Once Again (Middle)
On the ground, Caenis expresses disgust in Ophelia and decides to return to the temple. Koyanskaya decides to leave as well.
Caenis is incredulous Skadi allowed Surtr to be resurrected. Koyanskaya corrects her, saying Surtr was so antithetical to Skadi’s worldview that she couldn’t conceive of his existence. The moment Skadi failed to consider that the Lostbelt was finished. Skadi’s way of thinking also limited her Scandinavia’s potential.
Koyanskaya leaves the Lostbelt, expecting she and Caenis will next meet on the sea. Caenis remarks how Koyanskaya seeing herself as irreplaceable means she’ll be gone sooner than she realizes. She says Koyanskaya shouldn’t assume every Lostbelt to be on her side, calling her “pet”.
The heroes find they’re still alive thanks to Sigurd deflecting Surtr’s flames. Though they already know who he is, Sigurd introduces himself. He regrets he couldn’t resist Surt’s control of his body more than once. Mash realizes he is what barely stopped Surtr from executing Ritsuka.
Ortlinde confesses she is why Sigurd is still alive, having used a rune. Fortunately, the damage wasn’t as extensive as she believed, and it seemed like his wounds rewound themselves; Mash wonders if Ophelia was responsible for that. Ortlinde took that chance to keep Sigurd's Spirit Core intact, though she fears she will not last a few seconds.
At Ortlinde’s request, Sigurd heals Brynhildr, who is happy he is truly the hero she loves. He then reveals Skadi is why he could repel Surtr’s flames and why Brynhildr’s spear didn’t kill him. Skadi invites everyone into her castle.
With their masks gone, the giants are no longer under Skadi’s control and begin assaulting the villages as they resonant with Surtr. Skadi sends out the envoys to deal with them. She fears the villages’ protection will not last, though, if the giants’ power reaches its height during the Age of Gods. At best, she can keep the Bounded Field intact for half a day.
After Skadi confirms his deduction about the flames in the northern mountains, Holmes confesses to Ritsuka and Mash he had long suspected Surtr was involved. But knowing voicing his suspicions early would only cause confusion, he refrained himself from doing so. He also knew the Sigurd who attacked the Border wasn’t truly him, though he couldn’t convey that information at that time. As well, he regrets he didn’t try to convey the flames’ true nature or Surtr’s involvement.
Skadi calls the flames a testament to her weakness, unable to do anything about them even with Odin’s power. She reveals Surtr had gone against his fate of triggering Ragnarok to end the Norse Age of Gods to give way to the Age of Man, desiring instead to destroy the world.
He ate Fenrir, taking advantage of the wolf’s lowered guard from when he ate the sun, and gained his Authority of Niflheim. With his newfound power, he proceeded to kill god and giant alike. He then connected his true body, Muspelheim, to the sky through the hole where the sun was, destroying the nine realms as he attempted to incinerate the planet.
Odin and the remaining gods fought him to a stalemate. He then used a final rune to seal Muspelheim away as a false sun. Before passing, he fused the remaining god, Skadi, with Scáthach and entrusted his Primordial Runes to her.
To protect what remained from Surtr’s flames, Skadi covered the land with magical snow and ice, thus creating safe havens from the remaining giants for the humans who were left. With masks infused with her magical energy, she placed the giants under the authority she inherited from father, the giant Pjazi. She then created the envoys using the surviving Valkyries as a base.
Three thousand impossible years later, the Tree planted itself and Ophelia appeared. She told Skadi to grow the Tree for her world’s survival.
Holmes deduces Ophelia summoned Sigurd when Surtr used her Mystic Eye as a catalyst to infiltrate the ritual. He further deduces Ophelia saw Surtr’s soul with her Mystic Eye at some point.
He proposes to Skadi that they form an alliance to combat Surtr. But before Skadi can give her answer, the same unknown lifeforms the heroes encountered at Mt. Galdhøpiggen crash into the room from the northern mountains.
Skadi identifies them as Fantasy Tree seeds as she yells at them for invading her home, despite knowing she is corrected to the Tree. Furious they damaged her castle, she commands them to die, but they do not self-destruction to her shock. Sitonai appears and reveals Skadi’s connection to the Tree was severed.
After Sitonai destroys the seeds, everyone suspects Surtr is the new Lostbelt King. Skadi surmises Surtr intends to raze Scandinavia with his flaming sword, a Divine Construct designed to eliminate the Age of Gods from the planet until nothing remained. Da Vinci fears that destruction could reach outside the Lostbelt since Surtr still has the Paper Moon.
Skadi reveals the Tree is beyond the northern mountains, camouflaged with her snow and ice crystals. She then agrees to Holmes’s proposal to form a temporary alliance. She warns Sigurd and Brynhildr that the runes holding their Spirit Core together are fragile, so they’ll break if they expend all of their magical energy in battle.
Muspels emerge from the underground. After slaying them, everyone gets into Border and drive for the north. On the way, they contend with giants chasing them and Seeds raining down from the north to defend the Tree like Holmes suspects.
===Bringing Twilight Here Once Again (End)===
Surtr connects himself to the Tree to regain Fenrir’s Authority. He explains to Ophelia how he, the Fiery King of Giants, could hold Authority over ice. Ophelia sees invisible dragon wings growing from Surtr’s back, meaning he’s starting to manifest Fafnir.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Section 15: Bringing Twilight Here Once Again (End)
She watches as Surtr severs Skadi’s connection to the Tree and consumes it to restore his lost power thanks to possessing the Paper Moon. Her thoughts in a jumble, she agrees with Surtr’s desire to burn everything, feeling she at the very least will not cause Kirschtaria anymore trouble.
As Surtr raises his sword, he implores Ophelia to join him in burning everything away. Ophelia initially agrees, seeing that her wish will never be granted and her feelings will never be reciprocated, when she realizes Surtr inflicted her with Fafnir’s curse meant to restrain the target’s mind and soul. Surtr tells her it’s too late, for at least half of her soul has melded with him.
Surtr thwarted.png|Surtr thwarted from destroying Village 23

Napoleon disappearing.png|Napoleon Bonaparte disappears
Surtr tries to use Loptr Laegjarn to destroy Village 23, but Berserker, summoned by Sitonai, blocks it with the support of Ortlinde, Skadi, Sigurd, and Byrnhildr. However, they are struggling to even do that.
Mash tries to go help. Goredolf is against her going, though, finding the entire situation hopeless. But Ritsuka and Mash refuse to turn back now, for they have a responsibility to fulfill. Napoleon understands that responsibility is the same carried by those who move forward for those they left behind.
He relates the current situation to those who live in the Lostbelt, in that they’re both without hope. So for the sake of inspiring hope, Napoleon aims his cannon at Surtr’s head and fires his Noble Phantasm, Arc de Triomphe de l'Étoile, sacrificing his Spirit Origin and Spirit Core in the process. As he disappears, he encourages RItsuka to keep moving forward.
With his Imperial Privilege Skill, Napoleon establishes a telepathic link with Ophelia. He confesses he was summoned in response to her wish for someone to come and save her. He removes Fafnir’s curse from her as his last action and disappears, encouraging her to do what she truly wants to. Her mind restored and invigorated by Napoleon’s sacrifice, Ophelia escapes from Surtr to join the heroes.
She explains to the heroes that the Tree spreads its roots throughout whatever planet it’s planted on, spreading its Lostbelt’s reality. Surtr’s desire to burn the planet will therefore succeed if he isn’t stopped. Goredolf reluctantly agrees to a temporary alliance with Ophelia to stop Surtr, telling her she will be taken into custody once it’s over.
Ophelia confirms with Holmes that Surtr is dependent on his contract with her. Therefore, if it is severed, Surtr will be unable to maintain his existence efficiently, especially since he just used his Noble Phantasm and is currently healing from Napoleon’s attack. As it is her connection to Surtr, she destroys her Mystic Eye to sever their contract and remove his source of magical energy. She then uses the Sirius Light after imploring her Servant Sigurd to slay Surtr for her.
===Beyond the Gaze===
Supported by Skadi and Sitonai, the group ascend to fight Surtr. Sigurd hits Surtr with Bölverk Gram, which severely wounds the giant because his greed for destruction has made him Fafnir. This severs Surtr’s connection to the Tree and causes the Paper Moon to fall from his grasp. Skadi warns Surtr will regenerate in two minutes, so the heroes go to defeat Surtr before that happens.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Section 16: Beyond the Gaze
Sutr defeated.png|Surtr defeated by Sigurd and Brynhildr

Defeated, Surtr is appalled that he will perish at human hands. He identifies Ritsuka as the key to his defeat and decides they will fall with him. Brynhildr and Sigurd sever his arm before he can do anything, but Surtr has already he inscribed a death rune upon Ritsuka. He delights in Ritsuka’s death, only to learn it was an illusion created by Brynhildr’s rune. She and Sigurd then finish Surtr off at the cost of their lives. They disappear after reaffirming their love for each other and hoping they can help Ritsuka again someday.
Returning to the Border, Mash immediately goes to visit Ophelia in the infirmary. Skadi reveals the cost of Sirius Light is the user’s life, and absolutely nothing can be done to avoid it.
On her deathbed, Ophelia regrets she can’t see Mash grow even more. Mash helps her truly realize that she loved Kirschtaria. Ophelia is happy to see how Mash has grown, comparing Mash’s old self to herself and confessing to herself that she wanted to be her friend. She encourages Mash to keep moving forward, though she has mixed feelings about Chaldea thwarting the Crypters’ plans. She then dies, asking Mash to tell Napoleon “thank you“ and that “the rainbow was beautiful.“
A flashback shows after his marriage proposal was rejected, Napoleon promised to give Ophelia the best present she’ll ever get before his Spirit Origin’s time is up.
===Go, Beyond the Twilight===
Sitonai unveils the Tree to see that Surtr didn’t eat all of it. Skadi suspects it remained connected to its roots via a spatial distortion within Surtr’s body.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Section 17: Go, Beyond the Twilight
Ascending her own existence, donning the bridal gown she never got to wear as a battle dress, Skadi readies to defend her world from Chaldea now that her archenemy is dead. Ortlinde, following the example of her sisters, chooses of her own free will to protect the Tree with her. Hearing the cries of the ravens, Skadi promises to tell the Chaldeans their true identities if they defeat her and destroy the Tree. She then declares she will kill the innumerable lives of the Proper Human History for the sake of her world, refusing to let this miracle wither away.
Holmes deduces from her declaration that she knew her Lostbelt’s existence was abnormal long before Ophelia came and informed of the Proper Human History. Skadi confesses she knew her world was pruned away less than six months after Surtr’s broken Ragnarok was stopped. But then three thousand impossible years passed, though Skadi isn’t certain if the Tree was responsible for that paradox….that miracle. She only knows her land was reborn in the modern day, and to preserve it, she will make Proper Human History her enemy.
She laments that even after 3000 years, she still cannot support more villages beyond those created in the first six months. She can only support the lives of 10,000 humans, not even able to let them live onto the old age. Like Napoleon said, her world has no actual future, but even so Skadi still refuses to abandon it.
For three millennia, she has suppressed Surtr’s flames, but with him now dead, she believes her power can return hope to the land. She therefore revokes her love and challenges the Chaldeans to kill her if they wish to save humanity. Regretting how things turned out, Ritsuka and Mash fight Skadi and Ortlinde.
Ritsuka and Mash kill Ortlinde and defeat Skadi, followed by destroying the Tree. Holmes doesn’t understand, though, why Skadi fought the pair when they completely healed while she had barely recovered her magical energy from the battle with Surtr. Mash also says Skadi could have inscribed a death rune into them like Surtr tried.
Skadi answers her pride wouldn’t permit it, for she is obligated to protect this land and all that dwells in it. Because she needed to repair all the damage Surtr had done, she never had much magical energy to spare for her last battle.
She reveals the ravens are Odin’s holy raven, leading Goredolf to conclude that they are Huginn and Muninn. Skadi realizes Odin had them guide Chaldea this whole time and bemoans that he never guided her.
The Tree collapses, and while its destruction should have been impossible without a certain external factor, Chaldea was successful, presumably thanks to it becoming brittle from Surtr’s assimilation of it. Because most of Skadi’s spells hiding the Tree still remain, no human will see its destruction. Skadi reveals its name is Sombrero, suspecting the Chaldeans may know its significance.
Before she dies, Skadi has the envoys deliver her last commandment: the villagers are to stay in their home and go to sleep, though they will never wake up again.
Sitonai watches the Chaldeans leave the Lostbelt. She finds she is disappearing, even though, as Pseudo-Servant, she shouldn’t be able to disappear when the Lostbelt is gone and surmises that it is Skadi’s doing. She commends the envoys for delievering Skadi’s final commandment and disappears, hoping they can rest now.
Meanwhile, Gerda ignores Skadi’s final commandment and goes outside. She tries to imitate Fou’s hopping when in mid-hop the Lostbelt vanishes, disappearing before she even touched the ground.
=== Epilogue ===
Chaldea continues toward the North Sea, though everyone is depressed by how things ended. Goredolf regrets he said nothing more to Gerda and laments she will disappear with the Lostbelt like Russia.Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Ice-Flame Century - Epilogue
Holmes finds they were fortunate with their first two Lostbelts since their inhabitants were friendly to them and that was a great boon to their efforts. However, they cannot always expect that treatment, so they should be wary for when they’ll be treated as hostiles.
Goredolf understands destroying the Lostbelts is for humanity’s survival, but he cannot forget that they erased an innocent girl from existence. Meuniere wonders then if it would be best not to get involved with the Lostbelt inhabitants if it only results in depression.
Da Vinci tells him that would be turning away from responsibility, saying everyone has their own way of facing it. For Ritsuka, it is to get to know their opponent as well as possible so they can never forget them.
The emergency alarm suddenly goes off. There is a spatial fault 300m ahead: it is the ocean. The Border falls ten meters and the Chaldeans find themselves in the middle of the North Sea. With no means of getting out, the Chaldeans only wait to drown.
Suddenly they’re contacted by someone in the Wandering Sea, who identifies the Border and reveals the Paper Moon is theirs. They commend Chaldea for coming this far, meaning everything is proceeding within their calculations.
They then unveil the Island of the Wandering Sea, which is the first time in over 2000 years it has happened on a day other than New Year’s Eve. It didn’t appear on the Border’s radar thanks to it being a Folklore Defense.
The contact welcomes Chaldea to the Wandering Sea and introduces herself as Sion Eltnam Sokaris. She is a Spiritron hacker who escaped to the Wandering Sea when she predicted the world’s end and has been waiting for Chaldea's arrival. As she is the last remaining member of Atlas, the Wandering Sea’s higher-ups have entrusted her with resolving the issue of the bleached Earth.
