Yuggoth

Yuggoth is a planet located at the very edge of the Earth's Solar System in either the Kuiper Belt, Scattered Disk or even as far away as the Oort Cloud. It is the site of a Mi-go colony, a race of fungoid, crustacean-like extraterrestrials.

Yuggoth is a major stopping-off point for the Great Old Ones on their way to Earth. It has its own mini-solar system including Zaman, Nithon, the binary planet Thog & Thok and the Ghooric Zone. It orbits at ninety degrees from the plane of the elliptical. It is the natal home of an "Elder Race" of Yuggothians who died out (perhaps due to the cannibalistic habits of Cxaxukluth?) before the planet became an “outpost” of the Mi-Go territory. Relics of the Elder Race exist including, according to The Revelations of Gla'aki, a city of green pyramids, and a pit which might be “the Pit of Shoggoths”. A dark inhospitable world; its surface is ravaged by high winds, while its "seas" and "rivers" consist of a warm, oily substance which flows sluggishly under basalt bridges. Cities, towers and mines exist on both land and sea.
