Yuggoth
The Rim, Plutoid Outpost
A world at the solar system's edge, called Pluto by astronomers who measure only distance, base and mining colony for the fungoid Mi-go who trade in brains and silence.
Yuggoth... is a black, airless world far from the sun, where the Mi-go have their principal outpost.
Akeley correspondence, sealed packet, 1928
Overview
Yuggoth is the name the fungi from beyond give to a body the Lowell Observatory later called Pluto, a black airless world at the rim of the sun's dominion where mines plunge into rock older than terrestrial geology and ships depart for systems whose light has not yet reached Harvard's telescopes. It is not myth. It is infrastructure.
The Mi-go use Yuggoth as relay, factory, and courtroom for bargains that begin in Vermont farmhouses and end with brains in cylinders still able to speak. Human astronomy confirmed the planet's existence in 1930; human sanity has not caught up to what the confirmation implied about who was already there.
Description
Surface features, as inferred from whispered transmissions and the Akeley plates, include cyclopean towers without windows, landing fields carved from ice and basalt, and pits that emit a faint luminosity not accounted for by any known phosphorescence. The atmosphere is absent; the Mi-go do not require it. Visitors require surgery or translation into something that can survive the cold that is not cold but absence of mercy.
Cylinders shipped from Yuggoth contain preserved brains of scholars, poets, and one Vermont farmer who preferred the rim to death. The cylinders receive sensory input and transmit opinions. The archive has listened to three. It does not recommend the experience.
Historical Record
The 1928 Vermont horror established the Mi-go presence in the Green Mountains and their connection to Yuggoth via relay stations in hills that official surveys list as empty. Henry Akeley's correspondence and final disappearance supplied coordinates, formulae, and the warning that the fungi are not invaders but colonists returning to a system they mined before humanity learned fire.
Subsequent radio anomalies on certain frequencies match the 'whispering' pattern. Personnel who tune receivers to those bands without shielding report dreams of black planets and offers of travel without the inconvenience of the body.
Archive Notes
Do not accept Mi-go transportation offers. Do not ship brains. Radio monitoring of whisper bands requires rotation every seventy-two hours and psychiatric clearance. Cross-reference all Vermont disappearances with Leng and Yuggoth files. Pluto is not a symbol. It is a workplace.
