Mi-Go

''These creatures resemble giant lobsters with bat wings. Full sized mi-go are about 8 feet long and 6 feet tall. Warlocks who make pacts with Elder Gods can summon smaller versions of mi-go as their familiars.They cannot speak, but communicate by clicking their pincers. Creatures of superior intelligence from beyond the borders of our galaxy who mine certain areas on prime worlds for minerals not available on their home planet. The mi-go are pinkish in color, with crustaceous bodies bearing vast pairs of dorsal fins or membranous wings and several sets of articulate limbs. The mi-go have a sort of convoluted ellipsoid where its head should be, covered with a multitude of very short antennae.''

''The mi-go genus is unique in its ability to traverse the heatless and airless interstellar void in its corporeal form, though some of its variants do require mechanical or curious surgical transpositions to do so. They have organic wings which allow them free flight in space, though flight in our atmosphere is rather clumsy. Telepathy is their main means of communication. With surgical alterations of the vocal chords, the mi-go are able to speak human languages, though their voice is buzzy and irritating. The mi-go are advanced in the sphere of surgery and can successfully remove the brain of other species into silver cylinders for transportation to other worlds through space. The mi-go are physical beings and therefore killable, bleeding a strange, green ichor as blood. Dogs and many other unaligned creatures hate mi-go and will attack viciously.''
