Storm’s End is one of the strongest castles in the kingdom with its massive, rounded curtain wall a hundred feet high and as much as eighty feet thick on the seaward side. The great drum tower is keep, granary, barracks, feast hall, and lord’s dwelling all at once. The stones of the wall and tower are entirely smooth and placed so perfectly together that the wind can find no purchase. It sits hard upon a high cliff overlooking the sea, and there is a barred, watery passage through a cavern that leads beneath the castle.
Reputedly raised by Durran, the first Storm King, Storm’s End was built to withstand the terrible storms that came howling from the sea into Shipbreaker Bay. There are many legends concerning the castle, but one at least may be true—that the children of the forest used their magics in the raising, for the castle walls act as a shield from outside magic.
The last Storm King was the first to be defeated and slain by Aegon and his sisters, and his lands, titles, family name and arms, and even his daughter were given to Orys, illegitimate sibling to Aegon, as the first Lord of Storm’s End. King Robert Baratheon won his throne after leading a revolt against the Mad King, Aerys Targaryen. Their motto is, “Ours Is the Fury.”
