Harkyn Grymstone is a determined dwarven bounty hunter. Ever since his family was slain by a black dragon, he's sought revenge against all dragons, regardless of their nature. That's why he took a particular pleasure in his latest bounty: Kalec. Harkyn Grymstone has three odd companions in his team of fellow bounty hunters, Groth, Voll and Snee.
During the Scourge invasion at Tarren Mill, Harkyn found out that he was merely being used by Dar'khan to hunt down Kalecgos. He turned on Dar'khan and helped defend Tarren Mill.
