Dragonstone is the name of the island located at the entrance to Blackwater Bay and the castle thereon, which was shaped from stone to look like dragons. Dragonstone was the original seat of House Targaryen in Westeros, which they had colonized and fortified as the westernmost outpost of the Valyrian Freehold. After the Targaryen conquest of the Seven Kingdoms, the island in the Crownlands served as the seat of their heir apparent, known as the Prince of Dragonstone. After Robert Baratheon overthrew the Targaryens, he gave the island to his brother Stannis, creating House Baratheon of Dragonstone, the current ruler of Dragonstone.
