This castle is my version of Ajbbi's Besvärliga fästning. It requires customnpcs, carpenter's blocks, jammys furniture mod, and last biblocraft. You can still play without those mods but its will be empty, more blocky, and have no npcs. The npcs dont interact with you because I dont know how to do that, but you can trade with several of them. I didnt do much of the interior.
