I am currently working on a mod to upgrade the Sky Haven Temple. The first version which is currently on Steam changes the lighting a little, reduces the wind noise in the living quarters and adds two chairs to the large table in the main hall. I am using a mod called Sky Haven Temple 0 More Blades with it that adds a few generic Blades to make the place look less empty.
I am adding rooms to the temple. Have completed the layout of the living quarters and have a room for the Dragon Born but have yet to find a door and doorway for the quarters. Steps from this area lead lead down to a cavern area where there will be a smith, training area and possibly some other things. I want to add a grotto area open to the sky
A Blade Smith, scout and mage will be added. Their backstory is briefly this: Twenty years before the current events the great battle took place where all the Blades were killed. However the smith was away from the battle area at his forge and escaped, the scout was scouting and escaped. The mage was at the battle but was badly injured and left for dead. The scout found her nursed back to the point where she could heal herself and they returned to Sky Haven Temple. The smith also managed to get back there and the three of them have been living in the additional rooms.
At this point I have no idea how well the navimesh will work.
