Zemouregal's fort is a manor located east of Trollweiss Mountain, in The North. It is currently under the ownership of the Mahjarrat Zemouregal, and is believed to be his current base of operations. It can currently be accessed through the cellar by navigating Lamistard's Tunnels from the West, during and after The Curse of Arrav quest, or by entering through the front door from the Ritual site during and after The Ritual of the Mahjarrat.
During The Curse of Arrav, the player enters Zemouregal's fort but is attacked by Arrav. However before Arrav can be killed he is called away.
During The Ritual of the Mahjarrat, the player must use decoder strips to enter the front door. Once inside, the player must search a few crates to find the heart magic notes, which reveal that the further away Zemouregal is from Arrav, the stronger his resistance will be. Thus, he made a prism from a magical stone to strengthen his grip, but the stone failed to function. In the volcano on Karamja, Zemouregal found some obsidian, out of which he made a working prism. He hid in the fort to prevent the clumsy zombies from breaking it. The player overhears that Zemourgal's zombie army is in full strength, and that Arrav is in position. Lastly, the player smashes the black prism on the first floor, mentioned in the notes as strengthening Zemouregal's control over Arrav.
The fort is also used to store prisoners caught by Undead broavs that roam ritual site.
- Ironically, Zemouregal does not actually fit inside his fortress: His head sticks through the roof and the doors are much too small for him to use.
