Period attestation: lovecraft-1920s.
What sleeps is not dead; what is catalogued here may be doing neither.
Description
Chambersian origin; later mythos merges with Carcosa imagery.
Sensory reports conflict in detail — scale, colour, limb count — yet agree that the phenomenon offends proportion.
Olfactory notes in depositions: salt, copper, wet stone, and organic sweetness like fruit fermenting in a closed room.
Historical Record
Members stage forbidden plays; insanity spreads among audiences.
Post-1937 pastiche and game supplements multiplied references; the archive tags those layers expanded mythos unless a primary citation is supplied.
Cross-links at dossier foot should be treated as hypotheses, not as family trees carved in stone.
Cult Activity
Do not engage alone; do not accept hospitality from hosts who show windows to other eras.
Submit Form Theta-9 if conversation turns to cities remembered only in sleep.
