The Eclipse Order believes that Ayame's breaking of the cycle is a sign that the world is ripe for a new age of darkness. Led by a high priestess named Zarah, they aim to summon a being known as The Devourer, an ancient entity that existed before time itself. Zarah, once a powerful sorceress, believes that by releasing The Devourer, she will transcend mortality and become a god-like being. The Order seeks to manipulate the remnants of the prophecy Ayame rewrote, using it to their advantage.

Ayame learns that Zarah's power is tied to a series of Death Stones—artifacts created during the original ritual that bound Ayame to her curse. These stones were hidden in different realms and used to maintain the cycle of life and death. Now, the Eclipse Order seeks to gather them to unlock The Devourer's prison. Ayame realizes she must stop them before it's too late.
