Arc 29Britain’s Plague and the Lich King
Wang Hao ended the Holy Grail War, restored Black Jeanne, and connected Chaldea to the World Tree before turning to Britain’s corrupted National Fortune. As Lancelot’s plague and a buried taboo threatened the kingdom, Wang Hao declared himself the Lich King and offered to help the survivors confront the danger.
- Wang Hao and the World Tree defeated the Cthulhu Old God, and the tree’s growth produced Wish-Granting Shenron, whose wishes required both Counter Forces’ approval.
- Wang Hao ended the Holy Grail War, gave Black Jeanne a restored body and a crystal egg containing Fafnir, and sent Kariya Matou to the FGO world with gifts for his family.
- Wang Hao returned Olga Marie to Chaldea, planted the World Tree there, connected it to the River of Time, and established True Magic Battle Qi as Chaldea’s cultivation system.
- Wang Hao traveled to Artoria’s era and discovered that immense malice within Britain’s National Fortune was tied to an oceanic realm of corrupted worlds and accumulated evil.
- Wang Hao and Guinevere entered the Ahoge King’s camp, where Guinevere warned that Lancelot had unsealed the Evil God of Plague and the imprisoned Holy Beast White Fang.
- The Ahoge King named Mordred king of Camelot, then marched to the Bell Grassland as Wang Hao led more than ten million dead there and gathered Britain’s souls.
- Wang Hao declared himself the Lich King and attacked the Ahoge King and Mordred, while Guinevere told the defenders that White Fang could turn Britain’s dead into beings like Heroic Spirits.
- Merlin identified Lancelot’s target as the taboo power beneath the sea, and Wang Hao offered to teach a countering power while Merlin warned that it was far weaker than the oceanic taboo.
