The Dance of the Dragons is the upcoming House of the Dragon's civil war, fought between half-siblings, Queen Rhaenyra and Aegon II Targaryen. The claimants to the Iron Throne are supported by their factions, known as the Greens and the Blacks in lore and in the show's canon. Rhaenyra and Aegon have different mothers but the same father, i.e., King Viserys.
