Some mercenaries fight for a lost home, for revenge, for adventure. Drake MacBain fights for coin. No mission too dangerous, no battlefield too bloody, he’ll work for any of the warring nations of the Iron Kingdoms without moral qualm. MacBain fights with the gritty determination of the hired professional and will let nothing stop him from the completion of his contracts. He is the consummate mercenary and has the tools to finish any job.
