Grimnir

Grimnir is the warrior ancestor-god of the duardin, the Doomseeker: deity of fire, reckless courage, and the endless hunt. Where his brother Grungni built and sheltered, Grimnir sought only the greatest foe and the most glorious death, laughing into the teeth of any doom.

His defining legend is his last. In the Age of Myth, Grimnir hunted Vulcatrix, the Ur-Salamander and mother of all magmadroths, and the two titans met in a duel that cracked mountains and set the skies ablaze. Grimnir slew the great fire-beast, but the cataclysm of her death shattered the god himself, blasting his divine essence into countless glittering shards that rained across the Mortal Realms. That sacred metal is ur-gold, and every mote of it carries a spark of the fallen god.

From this myth rose the Fyreslayers, duardin lodges who hunt ur-gold with single-minded zeal and smelt it into runes hammered smoking into their own flesh. With each rune they take a fragment of Grimnir's divinity into themselves, and their zealots fight as living reliquaries, burning with borrowed godhood. Some dream that should enough ur-gold be gathered, the Doomseeker might one day be made whole and walk the realms again.

So Grimnir persists not as a single god but as a scattered, smouldering promise, worshipped by mercenary warriors who sell their axes across the realms to fund the great reforging. Courage, to his kin, is the only true prayer.
