The Shayzia Ruin is a ruined castle and the former seat of power of the Shayzien House, which fell sometime during the War of the Five Houses. In the present day, it is occupied by a group of bandits, who've set up camp in the area.
A broken altar, nearly identical to the broken sun altar in the Forthos Dungeon, can be searched for an ancient letter from the early days of the War of the Five Houses.
Shayzia Ruin is a possible meeting location that can be issued by Captain Ginea in the Intelligence Gathering minigame.
