HBO shared a poster for the Game of Thrones prequel series House of the Dragon featuring Emmy D’Arcy. The new art features D’Arcy as her character, Princess Rhaenyra Targaryen, and a dragon, with the caption: “Fire will reign.” Rhaenyra is the eldest child of King Viserys I Targaryen (Paddy Considine) and the niece of Prince Daemon Targaryen (Matt Smith).

House of the Dragon is based on the George R.R. Martin book Fire & Blood. The series takes place 200 years before the events of the HBO series Game of Thrones, based on Martin’s A Song of Ice and Fire book series.

House of the Dragon explores the events leading up to the Targaryen civil war, known as the “Dance of the Dragons.” Olivia Cooke, Steve Toussaint, Eve Best, Fabien Frankel, Sonoya Mizuno and Rhys Ifans also star.

House of the Dragon premieres August 21 on HBO.
