Template:SkyrimForts It occupies a mountain pass north of Windhelm and south of the Shrine of Azura, along the main road that travels from Windhelm to Winterhold.
The fort is composed of a courtyard, a prison and the captain's quarters. A ritual table is found at the very top of the main structure, accessible by a ladder located in the Captain's Quarters.
The fort is initially inhabited by a group of Conjurers and Necromancers along with several skeletons. If the Dragonborn sides with the Empire during the Civil War, the fort will be inhabited by Stormcloak Soldiers after assignment of the Rescue from Fort Kastav quest. Once completed, the fort will be garrisoned by Imperial Legion soldiers. The fort is not initially garrisoned by soldiers if the Civil War is won by the Stormcloaks; however, if the fort is cleared of mages, Stormcloak soldiers will garrison the fort once more after an in-game week.
Although the main road does not go through the fort itself, its close proximity makes it difficult to travel the road without being noticed and attacked if the fort contains enemies.
Enemies
- Skeletons
- Master Conjurer
- Necromancers
- Stormcloak Soldiers (during the Rescue from Fort Kastav quest)
