Set nearly 200 years before the events of Game of Thrones, Dance of the Dragons dramatizes the Targaryen civil war that erupts after King Viserys I’s death. His daughter, Rhaenyra, and his son by a second marriage, Aegon II, both claim the Iron Throne. The realm splits into two factions—the Blacks (Rhaenyra) and the Greens (Aegon II)—leading to a devastating war marked by dragonfire, shifting alliances, and the near extinction of House Targaryen’s dragons.
