The World of Emptiness is the home dimension of demons and monsters, some of which manage to cross into our dimension, wreaking havoc. The beings summoned by the Pale Gate Rune also hail from the World of Emptiness. The Gate Rune, one of the 27 True Runes, holds the ability to open portals to this dimension and other strange beings, such as Yohn, also reside within this place. The villain Yuber is said to be from here, as he exudes many non-human traits and is capable of summoning legions of monsters.
