Seven Kingdoms: Seowyn's Crossing
Greatwall Keep is one of the chief fortresses of the Summerwall. Soldiered largely by Summerling and Kalrentai warriors of Bulette Company, it acts as the checkpoint on the great north-south Crownway that runs from Sigurth’s Climb through Summerlund to Gwyllan’s Watch.
Boasting massive walls that connect to some of the natural mountains surrounding it, it has not fallen in any of the 300 years since the Summerwall was built. A small town has grown up in the courtyards between the walls, servicing the huge number of soldiers that live and guard the walls.
