Overview
Expedition register ME-1936-V92/8953 — cross-index under slug `the-legacy-of-cthulhu-core-rulebook`.
The dossier for The Legacy of Cthulhu core rulebook opens with a warning we did not write for ornament: several observers who sought direct contact ceased to file reports in languages the University recognises.
The Legacy of Cthulhu core rulebook belongs to that class of powers the vulgar call gods and the archive calls liabilities — dormant, local, or oceanic, yet never domesticated.
The Necronomicon is quoted too often as gossip; when a dossier cites Alhazred, demand the edition and the translator. Our English paraphrases deliberately blunt the lines that injure readers who memorise instead of understand.
What sleeps is not dead; what is catalogued here may be doing neither.
Description
Scale estimates in the files range from human to architectural, which usually means the observer was not the unit of measure.
Sound, when recorded, has been described as wet leather, glass harmonics, or bees inside a skull; analysts note infrasound may explain some, not all.
Several accounts mention a pressure change before sighting, as though the air admitted something larger than the room.
Historical Record
Earliest stack mention is a photocopy of a photocopy of Latin marginalia — chain of custody unsuitable for court, sufficient for caution.

High Priest of the Great Old Ones
A colossal entity of draconic and cephalopodic aspect, dreaming in death-like slumber beneath the Pacific until the stars align, and when they do, the world will know madness again.
