Raus

Raus ("created") is the universe Heart Realm takes place in. It was created by the Ahntir.

Raus is made up of three different realms, or layers of reality: Ilramir is the spirit realm, Vimilrah is the realm of the living, and Nemilrah is the realm of the dead. Each realm is layered on top of each other, but only the Ahntir and Ahntiri can see beyond the realm they're in and freely pass between them.
