Thassarian was the first death knight to rejoin the Alliance. He was first encountered in Acherus: The Ebon Hold as a level 55 standing next to Orbaz Bloodbane and Koltira Deathweaver. In phase two after completing  , he relocates to the Scarlet Tavern with Bloodbane, where he is involved in the following quests:
He shows up at the Battle for Light's Hope Chapel as a level 60 elite taking part in  .
Thassarian can later be found aboard the Alliance airship Skybreaker above the skies of Icecrown. He is involved in quests that unfold The Shadow Vault among others. He also plays a part in the unfolding storyline of the Wrath of The Lich King.
Even while he was in service of the Lich King, Thassarian seemed to be a noble person. After sending the player to rescue Koltira Deathweaver — against the code of the Scourge death knight — Orbaz Bloodbane asked why he cared, also insinuating his dislike of Koltira as he was a blood elf. Thassarian replied that, though they may have been hated enemies in life, "In death, we are brothers."
He appears to dual wield the Two-Handed Sword, Endbringer.

All I ever wished was to serve my king once again. For humanity, against a common enemy. Instead, I find that our numbers have been infiltrated by cultist scum.... and all of the signs point to Naxxanar as the origin of this rot.
