The Deepclan Reavers

Exile Stoneborn clans who quarry the dead Imperium's barrows for bronze and kill any who would stop them.

Cast out of the deep holds for oath-breaking, the Reavers took the one trade no honest clan will: they break open the Imperium's barrows and melt the grave-goods of the honoured dead. Bronze is bronze, they say, and the dead do not spend it. They smith as well as any Stoneborn and fight in a wall of stolen armour, which makes them far worse than common robbers. Borin Clan-Breaker leads them, who was named for breaking his own clan's oath first and has been breaking other people's ever since.
