I want this castle to be dark fantasy themed! I want it made from stone like blocks! I would prefer if the castle was made from darker stone blocks to fit the dark fantasy theme. I also want the interior to be made for me! The interior should have an enchanting room, storage room, bedroom, prison cells/dungeons, alchemy room, and an outside courtyard where I would grow my crops. I want the bedroom to have a balcony.
