You should build a floating island with a large,tall tower,each floor of the tower has a room it could be kinda like a medieval hotel ^_^...on second though forget the floating island you need the tower tall...wait a second...make part of it go underground and an underground tunnel to another tower. You wanna has the tower as tall and big as possible....and you should has a hole bunch of towers with tunnels to each other it would be epic :D if you do this can you make a multiplayer server with it on it? pwease :3
