Chaat (alternate spellings: Cthaat, Cthäat, also called The Dark Water God)

Origin: "The Plague of St. James Infirmary", by Ken Asamatsu, 2005? (Evidently inspired by Derleth's elemental mythos.)

In the Mythos

""Gh'neri nryu, hyanste wg'neh, Chaat!" They chanted the spell of the water god. The ankh fell near the base of the infestation of heads.... The gigantic god formed from the water of Lake Michigan began to spread out its arms...."
— Ken Asamatsu, "The Plague of St. James Infirmary"

An amorphous, shape-shifting, manifestation in the form of dark, iridescent water ooze, Chaat may assume the watery shape of the caster when summoned or contacted, otherwise Chaat is formless. Chaat might temporarily wield extended cones of water to whip its victims from distance, but prefers to crush things caught in its mass by altering the density and pressure of the water it infests. While the Chaat Aquadingen bears its name in the title the book, there is only a brief discussion of the water god and in some versions of the book the mention of Chaat as a god is missing all together.

Heresies and Controversies

  • Vague references to Chaat found in Cultes des Goules suggest that Chaat may be a powerful "water elemental". (August Derleth)
  • Chaat is nothing more than the physical, material manifestation of Shadow, a being that itself has no self-awareness or understanding of who or what it is. (Apex Evolved)
  • Chaat may be an avatar of, alternate name for, or member of the same alien race as Dagon and Hydra and/or Cthulhu; the manifestation of Chaat known as "Dagon" only resembles a Deep One when summoned by Deep Ones.
  • Chaat may be an especially large, ancient, cunning, and powerful protoplasmic ooze, worshipped as a god, and instinctively imitating the form of its summoner.
