Corneria Castle, as its name suggests, is a castle built in the town of Corneria. It is resided by the current King of Corneria, Steve, his wife Jane and their daughter Sara. King Steve claims to have built the castle by himself, even though it looks centuries old. (King Steve says he "built it that way.") The castle is guarded by Corneria Guards. The castle has a very rich interior, with gold-plated walls and famous paintings, including the Mona Lisa. However, Thief took all of it from the walls. It also contains a royal waiting room where subjects wait to see the king in the throne room.
