===Cosmos in the Lostbelt===
====Prologue====
On December 31, 2017 after Chaldea's apparent shutdown, it covered the CHALDEAS Earth with a branch dome, latched the Fantasy Trees onto the Earth and then 12 hours later she stretched the branches down to the surface in order to annihilate the entire humanity, almost succeeding in the process.Fate/Grand Order: Cosmos in the Lostbelt - SIN: Land of Unified Knowledge, Prologue After three months rewriting the World's Texture, it dispersed the branches, leaving the planet in a blank state and isolated from the universe, where the Lostbelts eventually expand and engulf it, usurping the Proper Human History.Fate/Grand Order: Cosmos in the Lostbelt - Anastasia: Permafrost Empire, Prologue
At some point the Alien World summoned Senji Muramasa as one of its apostles to ensure the "God" descent can proceed as planned.Fate/Grand Order: Cosmos in the Lostbelt - Olympus: Interstellar Mountain City - Section 17: My Thunder Which Tears Stars Asunder（II）
====Traum: Death and Revelation World====
Due to the first apostle's failure to take Chaldea out of the picture, the Alien World summoned James Moriarty to remind the detective of his original role or punish him for his betrayal or perhaps both things.Fate/Grand Order: Cosmos in the Lostbelt - Traum: A Certain Phantasmal Life and Death - Section 3: The Sin of being from Proper Human History
==Abilities== 
The Alien God is capable of wiping an entire planet's surface and completely destroying Earth's governments in mere days, as well as isolating the planet from signals, cosmic rays and other emissions from celestial bodies except the Sun. It is also capable of rewriting the Texture of a world and fixing existences such as the Lostbelts to it. It and it's Fantasy Trees can maintain the existence of a Lostbelt, which would normally be pruned as a dead-end history. Ophelia Phamrsolone hypothesised that the blank period between when a Lostbelt was pruned and when it was “replanted” in the present day takes place within each Tree. She suspects the Trees take the point that a Lostbelt’s history is pruned and simulates what would happen if that history had continued on from that point. The Trees thus effectively prove that history’s existence and project the result onto the planet’s surface. If Ophelia’s hypothesis is correct, that would mean the Trees are essentially creating history, which not even a Chief God who once ruled the planet could wield such Authority on Earth in the present day, especially as the Trees can support multiple Divine Spirits and even living Gods and their concomitant Authorities in modernity.Fate/Grand Order: Cosmos in the Lostbelt - Olympus: Interstellar Mountain City - Section 18: I Am the Thunder that Smites Stars (I)
It can also bestow certain privileges on other entities, such as the ability to travel between the Lostbelts, which it granted to the Apostles of the Alien World,Fate/Grand Order: Cosmos in the Lostbelt - Götterdämmerung: Eternal Flame Century, Prologue and bequeath unique abilities to any being it desires, since Douman claims most of his abilities are its blessings,Fate/Grand Order: Epic of Remnant - Shimosa Province: The Stage of Rivers of Blood and Mountains of Corpses - Section 2: Purgatorio (Middle) as well as the ability and sorcery to summon and corrupt Heroic Spirits that the "Sorcerer" boasts stems from it as well. Additionally it could also manipulate the human mind and place unique "curses" unto any individual it desires, as seen where it gave Kirschtaria Wodime a unique condition where he would constantly go through highly accurate, realistic simulations of him completing the Grand Orders with his teammates and Ritsuka Fujimaru, that then made him privy to several of their secrets, personalities and quirks.Fate/Grand Order: Cosmos in the Lostbelt - Olympus: Interstellar Mountain City - Interlude IIFate/Grand Order: Cosmos in the Lostbelt - Olympus: Interstellar Mountain City - Section 18: My Thunder Which Tears Stars Asunder（III)Fate/Grand Order: Cosmos in the Lostbelt - Olympus: Interstellar Mountain City - Section 25: Something One Is Not Born With
