The Prophet Tharon'ja is the last boss of Drak'Tharon Keep. He is a large skeletal wind serpent much like the Avatar of Hakkar. The Prophet Tharon'ja is known for ripping the flesh from the bones of some of the most formidable ice troll warriors. From the upper tiers of the fortress, Tharon'ja watches as waves of undead trolls pour from the keep's corridors to bolster the Scourge ranks in their assault on Zul'Drak.
