Storm's End is a fortress on the east coast of Westeros. The ancestral seat of House Baratheon, it lies just inland of Shipbreaker Bay and is one of the most impenetrable castles in the series. According to legend, it has never been successfully seized or destroyed by a storm. At the start of the series, it belonged to Renly Baratheon, to whom it was granted by his brother King Robert. Stannis Baratheon felt that it should have been given to him, and seized it during the War of the Five Kings.
