Doom Reavers: Barbarian Path

From publisher blurb:

Doom reavers walk the path of the condemned. As punishment for their crimes—whether they are truly guilty of them or not—these warriors are chained to fellblades, dark relics of the Orgoth era that twist the bearer into a bloodthirsty berserker, though a rare few manage to maintain a fragile hold on their sanity during this metamorphosis. Those doom reavers who do can rise as true legends in the Iron Kingdoms.
