House of the Dragon 3 trailer hints at epic sea battle and Targaryen war

The makers of the highly anticipated "House of the Dragon" S3 prequel to Game of Thrones finally unveiled the trailer on Thursday. June 2026 is when the third season is scheduled to premiere

The makers of House of the Dragon have finally dropped the gripping trailer for its third season, sending fans into a frenzy. The fantasy epic, set nearly 200 years before the events of Game of Thrones, continues to chronicle the bloody civil war within House Targaryen.

 

Adapted from George R. R. Martin’s novel Fire & Blood, the series delves into the rise and fall of the dragon-riding dynasty. Season 3, scheduled to premiere in June 2026, promises larger-scale warfare and political upheaval. Notably, a massive battle sequence originally planned for Season 2—trimmed to eight episodes—has now been shifted to the upcoming instalment. 

 

What to expect from House of the Dragon Season 3?

The trailer opens with Aemond Targaryen occupying the Iron Throne, signalling a dramatic shift in power following the turmoil of the previous season. With King Aegon gravely injured and Queen Alicent Hightower politically sidelined, Aemond appears poised to tighten his grip over King’s Landing.

 

However, the tides of war are far from settled. Rhaenyra Targaryen is shown strengthening her claim, with hints that she has secured new dragons to bolster her forces. The teaser also points towards high-stakes confrontations at sea, including what appears to be the long-anticipated Battle of the Gullet — a pivotal clash that could alter the course of the Dance of the Dragons.
