Blackwater Bay

The bay opens on the eastern coast of Westeros, a natural gateway from the Narrow Sea into the heart of the Seven Kingdoms. The Gullet marks its outer edge, a narrow passage between Sharp Point and Massey's Hook, with Dragonstone watching over the approach.

Within the bay rise headlands and shoals that sailors call the King's Pescadilla's Harpoons: for every rock that breaks the surface, a dozen more lie hidden below it, and crossing that stretch blind means risking the ship. Ships of the royal fleet of the Iron Throne patrol these waters to keep them clear of piracy.

Besides King's Landing, the bay holds other ports: Duskendale, which takes the overflow when the capital's traffic runs too heavy, and Driftmark, the largest island in the bay and seat of House Velaryon.

In 299 the mouth of the Blackwater Rush, where the river meets the bay, was the setting for the battle between the fleet of Stannis Baratheon and the royal navy of Joffrey Baratheon.

Tyrion Lannister, then acting Hand of the King, had ordered a great chain built to seal the river off from the bay. With Stannis's fleet trapped upriver, wildfire caught and destroyed much of it.
