The Abyss, also known as The Infinite Layers of the Abyss, or Demonholme,[1] is one of the planes of existence in Dungeons & Dragons. It is chaotic evil in alignment, and best known as the home of demons, including the numerous varieties of tanar'ri.

Layers of the Abyss

The Abyss is unique in that it is divided into an uncountable number of independent planes. Each has its own unique and terrible terrain.[1] Controlling at least one level of the Abyss usually qualifies a demon to claim the rank of demon lord.[2]

The numbering system used was developed by the Fraternity of Order, a guild of planar explorers who simply numbered the layers in the order they were discovered. In practice, worlds with physical connections tend to have adjacent numbers, and realms with a higher number are more distant from the first layer and thus harder to reach.[3]

While historically it was believed that there were precisely 666 layers of the Abyss, it is plausible that there may be even deeper and more inhospitable layers which no human has ever successfully explored and returned to tell the tale.
