This is a mod that I created to go with Castle Gonduin by DarthWayne - http://www.nexusmods.com/skyrim/mods/63801/?
If you don't have it I highly recommend it.  That being said It doesn't require the mod.
      The entrance is a cave east of Riverwood.

      I always found crafting and gathering materials tedious, So I added a semi immersive labyrinth that would take care of any crafting needs.
I've customized the texture for all the crafting station except for the smelter. I've also created four custom crafting/mining stations , with their own meshes as well.
      Each station and custom creature/object has a book pedestal with a journal entries to explain their lore. 
It also has a follower named Sarah who is a fire mage, she is marriable and essential, shes wearing AlanovichRomanov's Golden Saints Armor, Ive customized the texture, and added BBP.
     

This file requires all the DLCs and xp32-skeleton



All criticism welcome.
