Excalibur (Lostbelt)

In the British Lostbelt, the six Fairies of the Beginning refused to forge the Holy Sword Excalibur out of laziness, which resulted in the White Titan Sefar destroying the entire World during 12,000 BC. The Fairy of Paradise Aesc was originally created by the World to force the fairies of Britain to repent and complete their duty of forging Excalibur via Avalon le Fae. However, Morgan was never able to accomplish forging the Holy Sword, so Artoria Caster was created as her next generation to fulfill Morgan's old mission instead.Fate/Grand Order: Cosmos in the Lostbelt - Avalon le Fae: The Moment a Planet is Born, Section 27: Time of Creation
After completing her pilgrimage, Artoria Caster traveled to the Site of Selection in Avalon. However, she didn't end up becoming a new Holy Sword for Chaldea to use. Thanks to Senji Muramasa's sacrifice, she gained a new Magecraft theory: Holy Sword Creation.Fate/Grand Order: Cosmos in the Lostbelt - Avalon le Fae: The Moment a Planet is Born, Section 28: The Moment a Planet is Born With her power awakened, everything that she creates will end up gaining the "sword"-attribute.Fate/Grand Order: Artoria Caster Profile (After Lostbelt 6), Translated by Master of Chaos

===Dragon Vein Burning Armament===
 is a Spell used by Artoria Caster in the British Lostbelt.
After failing to kill Cernunnos with Rhongomyniad: Spirit Vein Closing Armament, Artoria determines that while the lances may be beyond her control, she could still make use of their structure. Comparing Rhongomyniad to a gun turret, all Artoria needed was to load them with different ammunition. In this case, the "Essence of the Holy Sword". Artoria then changes the Magic Circuit used from Morgan's Throne to her heart, and the Magical Energy from Camelot to herself, resulting in the ritual changing from Rhongomyniad: Spirit Vein Closing Armament, to Excalibur: Dragon Vein Burning Armament. Using all the magical energy that maintained her form, she launched the 12 Rhongomyniads at Cernunnos simultaneously. This evaporated 90% of his Curses layers and damaged its body enough to reveal its Divine Core.Fate/Grand Order: Cosmos in the Lostbelt - Avalon le Fae: The Moment a Planet is Born, Section 29: A Prophecy
===Hopewill Camelot===
 is the Noble Phantasm of Summer Artoria Caster.
Rhongomyniad, the spear built in the Capital of Sin Camelot to protect the Land of the Faerie Britain. This Anti-Calamity and Anti-Purge Noble Phantasm reenacts that ritual. It is what was used to cleanse the Calamity of Curses in the British Lostbelt. A combination technique of Excalibur and Rhongomyniad. 
It is also an advanced boundary Magecraft that is limited to a 'single' target that causes no harm to anything else even though normally the explosion would spread to a wide area due to the amount of mana it contains. It deals bonus damage to those with 'Chaotic', 'Divine', and 'Threat to Humanity' traits. Only when handling this Noble Phantasm does she not get carried away by the liveliness of Summer; she is the 100% pure 'Child of Prophecy' and becomes the 'Guardian of the Holy Sword'.Fate/Grand Order - Summer Artoria Caster's profile translated by Konchew at Reddit
===Hume-Barrel Rayproof===
 is a cannon equipped on the Storm Border after the events of the British Lostbelt. It was created using the Artoria Caster's Excalibur formula to take down U-Olga Marie. However, despite getting a direct hit, U-Olga Marie survived. She was able to transmute the shot of the main cannon into energy and absorb it, powering up even further in the process. Sion Eltnam Atlasia was puzzled by this, as she had made the Rayproof under the assumption that she could do that. Normally, a Beast would be recognized by the Holy Sword as a Threat to Humanity and thus it would receive the full power of the Earth against her, however, for some reason she does not register as a Threat and thus the Holy Sword was much weaker than it should be.Fate/Grand Order: Cosmos in the Lostbelt - Nahui Mictlan: Golden Sea of Trees Travelogue - Section 1: To the Land of the Dead It is later implied that her resistance to the Holy Sword is because she and those connected to the Alien World and Marisbury Animusphere's Grand Order are not considered enemies of the Earth, but rather allies of Earth and enemies of the universeFate/Grand Order: Cosmos in the Lostbelt - Nahui Mictlan: Golden Sea of Trees Travelogue - Section 19Fate/Grand Order: Cosmos in the Lostbelt - Nahui Mictlan: Golden Sea of Trees Travelogue - Section 23: Fifth Sun
According to TRISMEGISTUS II, destroying 60% of Lostbelt ORT's outer shell would weaken it enough so that a blast from the Storm Border's main cannon at point-blank range should finish it off. However, ORT was able to evade this attack with its Solar Storm by changing its trajectory.Fate/Grand Order: Cosmos in the Lostbelt - Nahui Mictlan: Golden Sea of Trees Travelogue - Section 22: The One Who Rules the Planet
