Ok so i described the huge overcomplicated castle i made earlier. Now i will talk about the more normal small castle. It would look like a sunken pirate ship. It would look exactly like a pirate wreck. There would be this cool thing though, when you get to the top deck, sometimes the captain's ghost would appear steering the boat. I also thought about a secret room in this one too, where somehow you would be able to enter a secret room where all the ghost pirates are, and then you can battle them. What would you think the small Celestia castle will look like?
