Princess Rhaenyra Targaryen is battling in a war in the House of the Dragon season 1 conclusion trailer.

The prequel Game of Thrones spinoff series on HBO has taken the world by storm and set new records for the streaming provider.

House of the Dragon, which is set several generations before Princess Daenerys Targaryen was born, is focused on the conflict that developed within the silver-haired, dragon-riding Targaryen family after King Viserys I Targaryen (Paddy Considine) designated his daughter Rhaenyra as the rightful heir to the Iron Throne.

Princess Rhaenys Targaryen (Eve Best), riding her dragon Meleys, bursts through the floor of the hall at Aegon's coronation in the Dragonpit and confronts the newly crowned king.

However, Lady Alicent Hightower (Olivia Cooke) is ready to withstand the impending dragon fire explosion as she steps in front of her son. Instead, Rhaenys directs Meleys toward the entrance before flying away.

In the House of the Dragon season 1 finale trailer, which debuted recently on Game of Thrones, Rhaenyra is shown fighting Aegon and his family.

In the video, Rhaenyra and Prince Daemon Targaryen (Matt Smith) are seen gathering their allies and getting ready for the impending catastrophic fight.

The season one conclusion teaser shows Rhaenyra learning of her father's death and the unexpected betrayal of Alicent, an old childhood friend with whom she appeared to have made amends just days earlier.
