 The article "The Sunset World" by Stephen Inniss in "Dragon" #150 (October 1989) presented a world that had been completely ravaged by mind flayers.The "Dragon's Bestiary" column, in the same issue and by the same author, described the "illithidae", the strange inhabitants of this world.The mind flayer appears first in the "Monstrous Compendium Volume One" (1989), and is reprinted in the "Monstrous Manual" (1993).
