Storm's End is the seat of House Baratheon, the Lords Paramount of the Stormlands. The castle is located at Durran's Point on the northern coast of Shipbreaker Bay, south of Bronzegate and northeast of Griffin's Roost. The kingsroad runs north from Storm's End to King's Landing, the capital of the Seven Kingdoms
One of the strongest castles in the Seven Kingdoms, Storm's End was once the ancestral seat of the Storm Kings of House Durrandon extending back many thousands of years. The castle is said to be protected by spells woven into its very walls that prevent magic from affecting it or passing through it.
In the year 301AC, Storm's End was captured by the forces of Aegon VI Targaryen in the early days of the Second War of Conquest. Following the war's end, the castle and it's traditional lands and titles were granted to Edric Storm.
Storm's End is surrounded by a massive outer curtain wall, one hundred feet high and forty feet thick on its thinnest side and nearly eighty feet thick on its seaward side. It is composed of a double course of stones with an inner core of sand and rubble. The wall is smooth and curving, the stones so well placed and so perfectly together that the wind can find no purchase. On the seaward side, there is a one hundred fifty foot drop below the wall into the sea. There is no safe anchorage by the castle.
The castle itself consists of one huge drum tower crowned with formidable battlements, so that from a distance enemies can see what appears to be a single huge, spiked fist thrusting towards the sky in defiance. The tower is so large that it comfortably contains the granary, barracks, armory, feast hall, and lord's chambers all at once. It is said that there are spells woven into the stonework. The seaward side of the castle stands upon a high white cliffs overlooking the sea, and there is a barred, watery passage through a cavern that leads beneath the castle.
The godswood of Storm's End has a weirwood heart tree carved with a solemn face.
