The Void is Vacuo’s realm, created by Rei using the Essence in order to keep him contained so he doesn’t destroy the universe. It has been described by Seymour as the CosWon equivalent of Hell, a place worse than death itself. It lacks light, sound, feeling, and much more. After Rei’s judgement, the most sinful are sent to the Void, consumed by Vacuo. Vacuo has best described what it’s like residing in the Void as that in the time Earth has spun for one year, he has lived ten thousand.
