The Dance of the Dragons occurs after long-drawn-out years of waiting for the end of King Viserys Targaryen's reign. As seen in House of the Dragon, two scions of House Targaryen fail to resolve their differences in the late King's lifetime and want to place their blood on the Iron Throne. Divided into the Blacks and the Greens, the former are represented by Viserys' decreed heir, Rhaenyra, while the latter are represented by the late king's male heir, Aegon II.
