Battlehorn Castle ... man ... what a poorly done expansion. The basement feels like a maze, it doesn't have aspects that I believe it should have, well, not anymore. I made some modifications, enjoy. I would love if you could add your screenshots of you using my mod.
   I am open to sugestions and changes for this mod. The images in the gallery show all the changes I made. 1.0 refers to all the alterations at the 1.0 version, and so on, so ... check all the images.

Notes

- As I changed the layout of the castle, internally, for the most part, it is important that you finish all the related quests BEFORE instaling this mod, aquire all the furniture and kill Arielle Jurard, the Lich. This is just a precaution. You will probably do not have problems with the Arielle Jurard quest.
