The Sphere castle is high up by a few feet off the ground due to high building. One must make only a small leep to get to its doors, and for the foals there is a draw-bridge. There is shelter in the castle, and a small stream running under the drawbridge. Also, there is plenty of grass outside to eat. It resides in a wintery place, though so it makes it tough to breed and hard- despite the shelter- for foals to survive.
