Hagop was a member of the Black Company from before the start of the series to before Soldiers Live. He is rarely seen without his fellow Company member and eternal sidekick Otto. He, like Otto, is well known for surviving every fight he gets into but always receiving at least a minor wound. He was one of the last survivors of the "Old Crew" who had sailed aboard the imperial flagship, The Dark Wings, from Beryl, across the Sea of Torments, to Opal.

Hagop became one of the Captured imprisoned with in the Cave of the Ancients. After being freed, he died in Hsien of natural causes along with Otto.
