The Abyss is a world within the Infernal Realm, primarily inhabited by demons. Although it has a surface and a blood red sky, the majority of it exists as vast depths beneath the surface surrounding an unfathomable pit called the Great Pit or simply the Abyss. There are hundreds of layers, and although traditionally counted at six hundred and sixty-six, the actual number is uncertain.
- 405 - Mushroom Forest
- 406 - Barren trees
- 407 - Addanat. Does not intersect the Great Pit and can only be reached from the neighboring layers.
