Dovahkiin Keep -- by Shawkab
Remove all items before upgrading!
Hosted with permission from author.
Dovahkiin Keep V4.0!
- Added a few guards. They are aligned with Windhelm and Eastmarch.
- Forges should act as a Skyforge and there is a wood chopping block in the courtyard.
- Removed underscore in Cell EDID names because it's used as a delimiter in save game filtering.
- Fixed the Dovahkiin Keep exterior so there wasn't any terrain tearing
- reconstructed the entire Dovahkiin Keep exterior
- Removed changes to adjacent cells, specifically the Trap door to the Abandon Prison. The skeletons and the trap door were under a stone preventing the player from accessing them.
- Added a new Armory with over 100 Mannequins [WIP]

Known Issues:

- The NavMesh around the back part of the Keep needs more work
- The doors in the entrance have banners to player homes and areas like the Dovahkiin Hideout. These doors do nothing. I am not sure what to do with them yet. If a player has the Dovahkiin Hideout I would have to have another door in each location and it would get messy.
- The interior NavMeshes need more work.  The Mannequins will move around.  I'll update this for the next version.

Thanks:

Special thanks to MrJack on the Bethesda forums for his help getting the item collection script to work. Once I have time to add it, It will make retrieving items from the Armory and other areas within the keep much easier.
