Located high in the impassable World's End Mountains, the fortress is most likely an ancient Seraph outpost that was abandoned a long time ago, and reclaimed by Morcalavin in more recent times. After the failure of the Spell of Ascension, it became Morcalavin's primary base of operations and the prime bastion of evil in the world of Parthoris.
Numerous biological and magical experiments take place within the fortress walls. The player's main tasks to deactivate the six true Tomes of Power until only the fake one remains. Then, the player can infiltrate Morcalavin's chamber and confront the fallen Seraph directly.
