Domains: Living stone, deep silence, geological patience.
Era of ascension: Great Expansion. Cohort: current. Drmnuul coalesced after the Frost Fall, when the deep Hestrube colonies first coordinated a multi-decade migration through solid rock and discovered the practice required a witness who could keep time at the rate the stone kept it.
Worshipped by: The Hestrube. No other clan, no diaspora, no surface community — the Hestrube share their patron with no one, because the worship requires standing inside the colony's breath-rhythm for years before the patron will register a presence at all. (The worships edge is authored downstream on the worshipper, not here.)
The written name has no vowels. This is not a transliteration choice; this is the name. Hestrube speak it as the resonance a held breath makes against stone, a pressure-pulse in the chest cavity rather than a sound at the mouth. Outsider scribes mark the consonants and leave the rest, because there is no other way to render it. A Hestrube colony at full migration breathes in and out at intervals of fourteen to nineteen days; Drmnuul's pulse is the same pulse, and the migration itself is the prayer. A colony covers four hundred miles in fifty years. The stone parts ahead of them and closes behind. He is the one who keeps the seam true.
He is not a mountain god and not an earth god. The distinction the Hestrube draw is that other patrons treat stone as substance; Drmnuul treats stone as body. The colony itself is a slow organism whose skin is the rock and whose pulse is the migration, and the patron is the body's own awareness of that pulse, the long noticing that lets a Hestrube elder know, without instruments, that the colony has drifted half a mile north of the route and needs to be brought back. A migrant who fails to feel the patron's pulse is set aside from the migration, given an alcove in the colony's previous resting-place, and left with provisions and a stone-knife. Some return to the colony years later, having found the pulse on their own. Some are not found again. The Hestrube speak of both outcomes without distinguishing them; either way, the colony moved on.
