House Targaryen is a noble family of Valyrian descent that escaped the Doom. They lived for centuries on the island of
Dragonstone until Aegon Targaryen and his sisters rode their dragons to the conquest of the Seven Kingdoms.
House Targaryen ruled as the Kings of Westeros for nearly 300 years, until their ouster in the War of the Usurper.
Their seats were the capital city of King's Landing and the island castle of Dragonstone.
