A castle on top of a cliff-island in the middle of an ocean. Features fully furnished interiors and many fun and hidden areas. Enjoy!

I used WorldPainter to create the base map; a useful tool that can be found by clicking here.
I used World Edit to carve out parts of the cliffs and make some of the castle; click here to find its download info.
I used MrMeep's Shaders to take the cover screenshot, you can find them here. (I added the lens flare manually).
