Elseworlders

 * Shukhi-khushtori, "killing joke", the grey morass seizing upon Atlan. An intelligent, viscious substance, it seeks to introduce itself into the nervous system of its prey. Once within the brain or spine, it reproduces wildly, devouring both to do so. Once it has slain its host, it conquers its body from within, warping it impossibly.
 * Vhadtarhin-shukhi, "the worst joke", a rare condition in which the grey morass becomes aerosolized. Individuals enter an area and then report becoming itchy, become belligerent and confused, and fall dead, transforming as occurs normally following exposure to the shukhi.
