Thunder Axe Fortress

Thunder Axe Fortress is a stronghold occupied by the Burning Blade cult founded by Klass Metalfist. The fortress is located in northwestern Desolace and is now lead by Kohor. While they have lost the Hand of Iruxos years ago, they found a way to summon a very powerful demon named Nazargen. If summoned too soon though, he would be weak enough to be dealt with.

History
They once stored a powerful artifact known as the Hand of Iruxos within the fortress, which was used to open demon portals at Mannoroc Coven. The fortress also once housed the Sceptre of Light - an immensely powerful artifact that the Burning Blade stole from the naga. Azore Aldamort sought to recover this artifact for the Argent Dawn and did with the aid of an adventurer. Tyranis Malem resided here, a traitor to his people, and a keen pioneer in demonic magics.

From Lands of Mystery:
 * "Thunder Axe is the most remove Burning Blade hideaway in the land. Here warlocks practice their dark magic but seems to refrain from their demon-summoning ways, at least to the casual observer. While Thrall is aware of the cult's existence, he has thus far sent only a small contingent of orcs to the area. It is also rumored that a sect from Thunder Axe is allied with the Magram centaur against the Gelkis."
