House of the Dragon season 2 new trailer hints at a bloody Targaryen civil war to come. Watch

The new trailer teases the conflict between Rhaenyra Targaryen and the king's firstborn son, Aegon. Based on George RR Martin's novel Fire & Blood, the new season is setting up the book's storyline known as Dance of the Dragons, which pits the Targaryen family against each other.

The trailer sets the stage for the Targaryen civil war as King Aegon II usurps Rhaenyra's throne. The Blacks, led by Rhaenyra and Daemon, plan an invasion of King's Landing to claim the Iron Throne. Meanwhile, the Greens, those loyal to Aegon, plan a defence. The trailer features many shots of the fiery, bloody war to come and the political machinations along with what appears to be a visit to the Wall.

HBO's hit Game of Thrones spin-off House of the Dragon season 2, is set to premiere in June. The new season will continue the story of the Targaryen dynasty, which takes place nearly 200 years before the events in Game of Thrones.
