Illusion Arc

The Illusion Arc is the fourth major Arc since the creation of Arcanis, and is still currently progressing. It revolves around Yoketa and the figures of his past, who have come back for reasons currently unknown and have begun causing havoc in Arcanis.

Synopsis
In the beginning of the Arc, a cloud of toxic gas spread throughout the Academy, causing all of the students to die. The keepers, in desperation, sacrificed their sparks to ressurect all of the students, causing the Keepers to lose their connections with the plane, also causing the plane to lose it's connections with everything else.
