House Baratheon of Storm's End's sigil is a black crowned stag, on a gold field (Or, a stag salient, crowned, sable), and their words are Ours is the Fury, though Joffrey, Renly, and Stannis modify the banner for their respective houses. The castle will be seiged again by Lord Mace Tyrell and likely by others as the War of the Five Kings continues. Melisandre believes the castle to be protected by magic spells, and ask Ser Davos Seaworth to smuggle her inside its walls so her shadow assassin will not be repelled.

During the War of the Five Kings, Stannis lays seige to the castle and Renly's host arrives from the Reach to attack Stannis, but Melisandre uses dark magic to assassinate both Renly and Ser Cortnay Penrose, who holds the castle. After the Rebellion, Robert gave Storm's End to his youngest brother Renly, and gave Dargonstone to Stannis. The castle was seiged during Robert's Rebellion by Lord Mace Tyrell on the land and Lord Paxter Redwyne's fleet on the sea, but Stannis Baratheon resisted the seige with help from Davos, a smuggler that became known as the Onion Knight for sneaking past the fleet with a ship full of onions. Orys took Argella, Argilac's daughter, as his wife and began the Baratheon reign of Storm's End. During Aegon's War of Conquest, the last Storm King, Argilac the Arrogant, lost to Orys Baratheon in open battle by leaving the fortress. It repelled the Andals in seven failed seiges, though eventually the Andals married into the Durrandon line. Throughout history, Storm's End has been laid seige multiple times, but has never fallen. The storm god retaliated by destroying the first six castles that Durran tried to build, until a young boy who grew to be called Bran the Builder, constructed the seventh version of Storm's End, which has stood against wind and rain ever since. It was once the ancestral seat of the Storm Kings of House Durrandon, and in the Dawn Age, Durran Godsgrief supposedly won the heart of Elenei, daughter of the sea god and goddess of the wind. Storm's End is considered one of the strongest castles in the Seven Kingdoms.

The kingsroad runs north from Storm's End to King's Landing through the Kingswood.

Storm's End is the seat of House Baratheon, the Lords Paramount of the Stormlands and is located on Durran's Point on the northern coast of Shipbreaker Bay in The Stormlands.
