Vulthoom
Vulthoom — a Great Old One in the mythos index; cult traces and dream contagion documented under Miskatonic seal. Register ME-1923-Q54/5047.
Overview
Expedition register ME-1923-Q54/5047 — cross-index under slug `vulthoom`.
Vulthoom belongs to that class of powers the vulgar call gods and the archive calls liabilities — dormant, local, or oceanic, yet never domesticated.
Mars-linked entity in Clark Ashton Smith's 'The Vaults of Yoh-Vombis', also called the Flower of Death.
Period attestation: post-lovecraft.
The Library holds primary text; this dossier holds orientation — never the reverse.
Description
Inhales or drains life from cities; colonists on Mars encountered it in red-lit vaults.
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
Survivors describe a blooming, many-petaled horror that speaks with courteous malice.
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.
Field Observations
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.
If the name appears in dreams three nights running, withdraw from the case and request audit.
Archive Notes
Cite archive slug `vulthoom` in all cross-references. If the name appears in dreams three nights running, withdraw from the case and request audit.
