Thazan Stormbellow is a dragon-slaying Dwarf of great renown. He encounters the party attempting to break into Ambershard Manor in Season 3. After a vicious fight and nearly TPK'ing the party himself, Thazan backed down and opened the front door to Ambershard Manor himself. This was Thazan's only appearance in any Acquisitions Inc. storyline though he is presumably still alive.
Thazan joins combat with his loyal boar named Kortha who also survived contact with Acquisitions Inc and is presumably still alive as well.
