The Abyss is a realm of chaotic evil deep within the Elemental Chaos. It consists of uncounted layers swirling in a raging vortex. These layers are home to the demons which are pure embodiment of chaotic evil. Some powerful demons that lay claim to entire levels of the Abyss have become known as demon lords. The deity Lolth often resides in one of the layers of the Abyss known as the Demonweb.
