House of the Dragon

Season 1 Episode 7 - Eps 7: Driftmark

With almost 15 dragons under their control, the Targaryen dynasty is at its strongest in the prequel series. Most empires—real and imagined—fall from such heights. The Targaryens' long decline begins almost 193 years before Game of Thrones when King Viserys Targaryen breaks with custom and names his daughter Rhaenyra successor to the Iron Throne. When Viserys fathers a son, the court is startled when Rhaenyra remains his heir, sowing conflict across the country.
