Mind Flayers (Illithids)

Mind Flayers seem to have no creation or place of origin. All that is known is that they once ruled a cosmos spanning empire, were overthrown by a slave race, and plot from the shadows to recreate their star spanning empire.

 Illithids venerate an unimaginable evil imprisoned and slumbering within the Astral Sea. This being named Cthulhu bears a great resemblance to a large six-tentacled Mind Flayer with large bat like wings and a greenish coloration.

 Mind Flayers are at odds with many other aberrational races, for they have no wish to destroy the cosmos, they “merely” seek to bring darkness and domination to the world in preparation for the rise of Cthulhu’s city of Ry’leh from the depths of the Astral Sea.
