House of the Dragon S03E01

The prequel series finds the Targaryen dynasty at the absolute apex of its power, with more than 15 dragons under their yoke. Most empires - real and imagined - crumble from such heights. In the case of the Targaryens, their slow fall begins almost 193 years before the events of Game of Thrones, when King Viserys Targaryen breaks with a century of tradition by naming his daughter Rhaenyra heir to the Iron Throne. But when Viserys later fathers a son, the court is shocked when Rhaenyra retains her status as his heir, and seeds of division sow friction across the realm.
