House Targaryen of King's Landing is a noble family of Valyrian descent who once ruled the Seven Kingdoms of Westeros. The Targaryen sigil is a red three-headed dragon, breathing red flames on black.[1][2][3][4] The house words are "Fire and Blood".[5] The only family of dragonlords who survived the Doom of Valyria, the Targaryens left the Valyrian Freehold twelve years before the Doom. They resided for more than a century at Dragonstone castle on Dragonstone island, until Aegon the Conqueror and his sister-wives, Visenya and Rhaenys, began the first of the Wars of Conquest in 2 BC. During Aegon's Conquest, the family built the Aegonfort in the new capital city of King's Landing. The Aegonfort was later torn down and replaced by the Red Keep, which remained their main seat for the duration of their dynasty, and which housed the Iron Throne. Their original castle was almost always given to the heir to the throne, the Prince of Dragonstone. The Targaryens eventually built the summer residence Summerhall, which has been given to several younger sons of the family over time.
