Ghulmir the Vigil

Ghulmir was forged centuries ago by the cabal known as the Ledger-Matriarchs to guard the hoard beneath the Stone Reliquary of Halvorsen. When the Reliquary fell to betrayers and war, the Ledger-Matriarchs bound the remains of a dozen sworn keepers into a single guardian, pouring their ledgers of vows and curses into a carved iron mask. Over generations the ritual warped the guardian; it became less a faithful sentinel and more a slow, gnawing will that collects and preserves valuables by any means necessary. Scholars of funerary magic — notably the archivist Kest Thir of the Obsidian Ledger — argue that Ghulmir's hunger for new corpses and treasure is a side effect of the original binding ritual, which tied the guardian's sense of duty to the accumulation of material tokens of oath-keeping. It lairs in belowground vaults, collapsed crypts, and buried reliquaries where the air is stale and thick with the smell of metal and rot. Raiders tell of a "watcher with a mask" that can lull sentries into a stupor and close a vault door from the inside; the clandestine thieves' guild called the Whisper-Fold leaves offerings at ruined vault-mouths to avoid its attention.

Imagine a colossal, misshapen humanoid heap, nearly filling a vault's doorway: layered slabs of necrotic flesh stitched with rusted wire, pockets of jellied fat that wobble when it shifts, and strips of ceremonial cloth soaked and mummified into the bulging folds. The mask is an iron oval, pitted and rimmed with tiny carved sigils; behind a torn seam in the mask you can glimpse pallid, damp skin and teeth set in a half-smile. Embedded in its mass are bits of armor, buckles, coins, and the occasional skeletal hand that twitches. The surface is slick with putrid slime and small carrion beetles; steam of cold breath rolls from the seams. Scale reference: the creature should be drawn nearly as tall as a vaulted stone doorway (roughly two to three times the height of a standing human) with the mask set where a human face would be, and pockets of treasure visible in torn flesh cavities.
