Eternal Void

The Eternal Void is the dimension of the dead. There is no Heaven or Hell, just the Eternal Void. The Grim Reaper can visit the Eternal Void anytime, and interact with the dead.

Battle of Asgarnia
Since the Battle of Asgarnia, 95% of the combatants died and their souls are trapped in the Eternal Void. Even citizens caught in the middle have made their way to the Eternal Void.
