Abyss

The abyss is the lower plane in the Dreamscape and an area in the Astral-sea within the Planes of existence of Hir. It is considered a dangerous place to simply see and also a place one can accidently end up in. Many who have seen the Abyss walk away scarred and changed from the things they see, however sometimes they obtained new powers along with this insanity. The abyss is apparently inhabited by many horrors and unknowable beings that are leagues above the beings of Hir. Some scholars suggest they may not even realise Humanoids exist. The abyss in the end is the lowest plane a person can reach physically and mentally.
