Mindflayers (or Illithids, as they call themselves), are highly intelligent creatures from beyond the world. Birthed near the Stars of Ill Omen, where the Primordial whispers strange and horrible truths that twist space and makes foul things grow, the illithids congregate in dark places beneath the earth, occasionally enslaving surface dwellers to their wills. It is said that they seek The Song of Stars, or that they know pieces of it, or that the elder brains that control illitihd hives desire the Name of The Nameless One. Whatever the case may be, illithids are dangerous creatures who see mortals as little more than a food source.

An illithid is a strange creature, standing some 6 feet tall, that is humanoid only in the most general terms. Its flesh is rubbery and mauve, glistening with chill slime. The creature’s head looks rather like a four tentacled octopus, made all the more horrible by a pair of bloated, white eyes. Its mouth, a revolting thing like a lampreys maw, constantly drips an oily slime when it is not siphoning out the brains of living prey.
