Excerpted from Marge Hollander's Digest of Demons and Devils:
"The Ushtohc are an invasive other dimensional race. They insert a portion of their consciousness into innocuous everyday objects and remain hidden while their influence grows. They slowly infect the immediate reality with their presence until a suitable mobile host presents itself. Once they have invaded a mobile host, they are nearly impossible to exorcise without great psychic effort. Luckily, their transmission into the earth realm seems to only coincide with very rare celestial alignments."
