Mi-go, the Fungi from Yuggoth
They were pinkish things about five feet long; with crustaceous bodies bearing vast pairs of dorsal fins or membranous wings and several sets of articulate limbs, and with a sort of convoluted ellipsoid, covered with multitudes of very short antenna, where a head should ordinarily be…Sometimes [they] walked on all their legs and sometimes on their hindmost pair only. – H.P. Lovecraft “The Whisperer in Darkness”
The fungi from Yuggoth are an interstellar race, with a main colony or base on Yuggoth. There are mining colonies in the mountains of Earth, where the Mi-go seek rare ores. The Mi-go have definite connections with fungi, and are clearly not animal. They communicate with each other by changing the colours of their brain-like heads, but they can speak human tongues in buzzing, insect-like voices. They worship both Nyarlathotep and Shub-Niggurath, and possibly others. They hire human agents to simplify their operations, and are sometimes connected to cults.
They are technologically advanced using various equipment, including mist projectors.
First encountered during the events of Case 003 – The Madman.
