Crow's Nest is the seat of House Morrigen in the Stormlands. It is located in mountainous terrain between Griffin's Roost and Stonehelm, along the western edge of Cape Wrath and the rainwood.
A Dance with Dragons
The Stormlands are invaded with the landing of the Golden Company. While a quarter of the Golden Company's available strength is taking Griffin's Roost, Ser Tristan Rivers sets off to seize the seat of House Morrigen at Crow's Nest, and Laswell Peake for Rain House, the stronghold of House Wylde, simultaneously. Harry Strickland argues that if Rivers and Peake are successful the Golden Company will control a better part of Cape Wrath. The seat falls quickly.
