Quachil Uttaus, also known as the Treader of the Dust or The Ultimate Corruption, is a Great Old One which appears in the H.P. Lovecraft-inspired Cthulhu Mythos.
Description[]
A small humanoid creature, Quachil Uttaus resembles a skeletal mummy, bereft of hair, whose arms reach out in a constant grasp, as if searching for its next victim. It's touch is lethal, as even the slightest brush of its fingertips will instantly reduce a mortal creature to dust, through which Quachil will leave a trail of footprints. In addition, living beings in its presence experience an acceleration of time, hastening their death by old age.
Usually worshiped as a god of death, age, or entropy, to summon Quachil is to invite certain death if one harbours even the most abstract thought of ending one's own life.
