Harman was a Crimson Guardsman and part of the Second Induction. He was described as a hulking ex-Free City swordsman. His duties usually included simply standing and fighting next to Meek until they or their attackers were all dead.
Harman was with the Guard when they besieged the warlock Shen's fortress atop the Spur in Bael. He joined Greymane's force that broke into the Spur's central staircase where they confronted Shen directly.
With the end of the Diaspora, Harman's company returned to Stratem. There, he was part of a squad sent to reconnoiter the Guard's assembly point at Fortress Haven in anticipation of Lieutenant Skinner's arrival.
