The Wilderness Castle can be found near the road to Sargoza in the Wilderness of Betancuria. It is surrounded by a high wall with turrets and has a two story keep and towerhouse in it's yard. The original purpose of the Castle was presumably to control the main road, but it was abandoned following the Dhorn invasion of the city and the subsequent collapse of the bridge over the Great River. The castle is now inhabited by a small group of bandits. The Princess passes near the Castle during Lesson 7.
