When the group visits the Necropolis of Nostalgia, located at the bottom of Zaude, they find the City of the Waning Moon, where the souls of the Children of the Full Moon who sacrificed their lives reside in a realm detached from time and the reality of the world above. Deeper within, they find the king of the Children of the Full Moon, Ohma (オーマ Ooma?), who claims to be imprisoned. Long ago, the Entelexeia and ancestors of the Children of the Full Moon worked together to seal Ohma away for 1,000 years due to a conflict among the Children of the Full Moon. He only managed to stay alive so long thanks to a drug known as amurita (アムリタ?), which caused adverse effects and transformed him into a mutated creature.
