Abhoth, The Source of Uncleanliness, is an Outer God in the Cthulhu-mythos.
Abhoth is often described as a "horrid, dark gray protean mass" that serves as a source of all "miscreation and abomiantion". Similiar to Outer Goddess Shub-Niggurath, Abhoth is constantly spawning obscene monsters into existence, who are often simply grabbed by their parent and devoured again. The children who manage to survive, usually abandon their parent and wander off.
Like most Outer Gods, Abhoth is often beyond human-comprehension, though he is known to be at least of a twisted and cynical mind, similiar to Nyarlathotep.
He is currently residing in the cavern of Y'quaa beneath Mount Voormithadreth and, similiar tp Cthulhu, can influence others telepathically from a distance.
- Abhoth is a later addition to the Cthulhu-mythos by writer Clark Ashton Smith.
