  • Summon Monstrous Aid (1/Day). A mi-go priest may call an earth elemental � which appears as a cross between an eel and an octopus made from soggy fungus � but is otherwise treated as a normal earth elemental.


Mi-go are both scientists and colonists�extraterrestrial travelers from deep space who view the universe as a canvas to be mastered and controlled. Their numbers on any particular planet can vary, but taken on a galactic scale, are mind-numbing in scope.

Fungi from Beyond. Mi-go are unnaturally graceful creatures has a bulbous, lumpy head, spiny insectoid wings, and a tangle of spiky, clawed legs. Although a mi-go’s shape might suggest it is an arthropod, the creature is, in fact, a highly evolved form of extraterrestrial fungus. Mi-go communicates via a combination of clicking pincers and subtle shifts in the coloration of their bulbous heads. A typical mi-go is roughly the size of a human but weighs only 90 pounds.
