Ironoath
Forge-priests of the world's inner fire, who treat the world as sacred, infinite material and dig without end. Grudge-keepers whose mines kill the green above, and the one enemy the phantom elves have never learned to frighten.
Oathmaster of the greatest deep hold and keeper of a ledger of grudges older than most nations. Brokk fears nothing that walks the surface, least of all the elves, and has taken more of their forest than any before him. He tells himself the bargains struck near the Pit are bargains he controls, and is very careful never to count what he owes down there.
