Sitting on the Crab Isle just off the coast of Nys is Crab Keep, the ancestral seat of House Agenos. Dour, small, and bleak, Claw Keep is rarely visited by members of House Agenos in the modern day, with most members opting to rule the Gulf from the opulent city of Nys.
While unimpressive in appearance, Crab Keep is a formidable castle. Tunnels dug into the stone under the castle allow for easy escape from the castle to the mainland of Yekare itself. Indeed, some tunnels are said to lead to Nys, though this rumor has never been substantiated.
