Thunder Axe Fortress is a stronghold occupied by the Burning Blade cult founded by Klass Metalfist. Within the fortress they store the artifact known as the Hand of Iruxos, which is used to open demon portals at Mannoroc Coven. It is interesting to note that the red crystal containing the demon holding the Demon Box (which containts the Hand of Iruxos) may hypothetically be identical in its composition to bloodstone - material frequently used in summoning demons. Thunder Axe Fortress also houses the Sceptre of Light - an immensely powerful artifact that the Burning Blade stole from the naga. Azore Aldamort seeks to recover this artifact for the Argent Dawn. Tyranis Malem resides here, a traitor to his people, and a keen pioneer in demonic magics.
