The Lord of Dragonstone is the ruler of the stronghold of Dragonstone upon the Island of Dragonstone in Blackwater Bay. The ruler commands the loyality of Several vassal houses established on the islands of Blackwater Bay.
Dragonstone is the ancestral seat of House Targaryen. It was the westernmost outpost of the Valyrian Empire. Prior to Robert's Rebellion, the island served as the seat of the heir apparent, known as the "Prince of Dragonstone". The two titles were often, though not always, synonymous. The first Prince of Dragonstone was Aenys I Targaryen, son of Aegon I, while the last was Rhaegar Targaryen.
Dragonstone was given to Stannis Baratheon by his brother, King Robert after he won the Iron Throne. Since Robert did not grant his brothers the title of "Prince", Stannis was given lordship over Dragonstone instead. The last known holder of this title was Daenerys Targaryen.
After the Wars of Conquest, the ruler of the island and the castle of Dragonstone happened to be the heir prince of the Iron Throne, titled as Prince of Dragonstone, until the fall of House Targaryen.
