were wiped out by the pre-human settlers who migrated here from the south. These pre-humans built the first capital of Hyperborea, at Commoriom. Later they moved to Uzuldaroum, when prophesies foretold of Commoriom's doom. Gods Abhoth [H]e described a sort of pool with a margin of mud that was marled with obscene offal; and in the pool a grayish, horrid mass that nearly choked it from rim to rim... Here, it seemed, was the ultimate source of all miscreation and abomination. For the gray mass quobbed and quivered, and swelled perpetually; and from it, in manifold fission, were spawned the anatomies that crept away on every side through the grotto. There were things like bodiless legs or arms that flailed in the slime, or heads that rolled, or floundering bellies with fishes' fins; and all manner of things malformed and monstrous, that grew in size as they departed from the neighborhood of Abhoth. And those that swam not swiftly ashore when they fell into the pool from Abhoth, were devoured by mouths that gaped in the parent bulk. —Clark Ashton Smith, The Seven Geases Abhoth ("The Source of Uncleanliness") resides in the cavern of Y'quaa beneath Mount Voormithadreth. It is a horrid, dark gray protean mass and is said to be the ultimate source of all miscreation and abomination. Obscene monsters constantly form in Abhoth's gray mass and crawl away from their parent. No two of Abhoth's children are alike. In general, they are complex life forms, but the majority of them are simple-minded, acting on impulse. Their forms can be anything from amorphous blobs and singular body parts to queer humanoids and monstrous mutants. Abhoth's tentacles and limbs grab many of them, pulling them back and devouring them. Most of those that escape simply wander off; only a few of them tend to their sire's needs. Abhoth has a twisted and cynical mind and can communicate telepathically with others near him. Abhoth does not have any human worshippers, although an inhuman cult, known as the Unclean Ones, led by Yeb, is devoted to him. The demon lord Juiblex in the Dungeons & Dragons role-playing game is likely derived from Abhoth. Abhoth is one of the Ancient Ones in the board game Arkham Horror. He is included in the Dunwich Horror expansion. Abhoth is also mentioned in Colin Wilson's The Mind Parasites. Atlach-Nacha In the short story The Seven Geases
