Demon Realm

Overview
The world Demons come from.

The world is red and black, and generally sulky. The Demon Realm was basically a desolate black plateau under a red sky. There are too many clouds which are blood-red with a strange texture, so one could really touch them for real if one wanted to. The miasma is so heavy that even Evan felt it sting. Any being other than Demons receive a great debuff. Conversely, Demons receive a great buff.

Trivia

 * It and the Spirit Realm have both often been translated as Mana World.
