This is an ancient ruined castle situated on the edge of a cliff in the Crag Hills, just east of Luon. Historically, people have stayed away from these ruins. They were said to be inhabited by all nature of dangerous creatures. There was a long running rumour of a powerful Lich who lived in the old throne room.
This castle is now home to a goblin kingdom. They have actually been trying to interact with Luon diplomatically. This is hampered by the fact that they appear to be looting and burning random farms and small villages outside of the city.
