Brunna Drennak is a Drasnian smith taken into the Gorathi slave provinces, and a priest of Krondeum who never stopped being one. She was carried off the work of a clan-hall somewhere in the north, sold down through the navigation-fees that move slaves out of Tamadrez, and set to the forge that her captors keep busy with chains and legion-iron. Through all of it she kept the rite. She is the living proof of a thing the Iron of the Eternal March refuses to look at directly: that the war-faith's Hammerlord and the slave's forge-daemon are not two gods but one, read two opposite ways across the same anvil.
The rite she keeps is the dwarven one in full. A finished thing is carried to a fire and the hand that will carry it next is named aloud, and the naming is what makes the work whole. Krondeum's own custom answers the hard case directly: when the carrier a thing was made for is dead or gone, a substitute is named so the work is not orphaned. Brunna has had to use that custom in a way no clan-hall smith ever intended. The empire makes her forge slave-chains, and over the chains she forges she still performs the naming, naming as their carrier the free hand that will one day strike them off. It is the rite turned into an act of defiance so quiet her overseers have never recognized it as anything at all. She is not making chains. She is making, by the god's own logic, the future unmaking of chains, and she has named the one who will do it.
When Serel's schism reached the slave-quarters offering the daemon without the empire's reading, Brunna did not have to be converted to anything. She had been keeping that faith all along while the chaplains who owned her prayed to a corruption of it. What the schism gave her was permission to keep the rite in the open and a chaplain of the conquerors willing to stand between her fire and the Hammer-Primate's men. What she gives the schism is harder to replace: she is the one who can say, and mean it, that she worships exactly the god the Iron worships, and that the slaves have had him right the whole time.
