Illithocyte were illithid tadpoles that survived the fall of a mind flayer empire, and evolved into a new life form. They crawled about in groups seeking psychic radiation on which to feed.[1]

Following the demise of the city of Ch'Chitl, illithocytes appeared in the surrounding areas of the Underdark as a consequence of the death of the city's elder brain.[1]
