The dance of the dragons has only just begun, as House of the Dragon season 3 is on its way to continue the epic story of the war between Rhaenyra and the Hightowers.

HBO has pledged itself to the Game of Thrones prequel, announcing before the start of House of the Dragon season 2 that a third season had been greenlit. Throw in more critical acclaim (season 2 is "Certified Fresh" on Rotten Tomatoes) and the continued solid ratings for the show, and it's little surprise that HBO is flying high with its latest Game of Thrones series (and continuing to add to it with another prequel series, A Knight of the Seven Kingdoms).

But as we wait for House of the Dragon season 3 to return, here is everything we know about the next season.

House of the Dragon season 3 release date

There is no official release date for House of the Dragon season 3 and no announced timetable for the show's return as of yet.

It took two years for House of the Dragon season 2 to reach TV following the end of season 1, but there were outside factors that contributed to that delay (the 2023 Hollywood strikes). With no such hindrance this time, could we get House of the Dragon season 3 sometime in 2025? It's a big show, so production takes a long time, but you'd have to imagine HBO would want to keep momentum going on the series.

It was announced on March 31 that production was officially underway on House of the Dragon season 3, so that's the first step in getting it back on TV.

In the meantime, if you need to catch up on House of the Dragon between now and the series' return, US viewers can stream it exclusively on Max, while those in the UK can watch the show on-demand via Sky TV, NOW TV and Sky Go.

House of the Dragon season 3 plot

No official plot details about House of the Dragon season 3 have been announced yet, but we can infer a lot of things that are going to taking place in the third season based on where things left off with season 2.

Most critically, war is about to break out as armies for the Blacks (Rhaenyra's forces that include her seven dragons, Daemon's Riverlands army, Corlys' fleet and the North) and the Green's (Aemond and Vhagar, Criston Cole and the Hightower forces, which will include Prince Daeron, the Lannister army and ships from Essos). Rhaenyra is possibly going to add another dragon as Rhaena sought to fulfill her long desire for one as she chased down the wild dragon in the Vale.

Other big plot points that were left open-ended for next season include Aegon and Larys fleeing King's Landing to avoid being killed by Aemond. Also, Otto Hightower is imprisoned, though we don't know where.

If you can't wait to find out more about what's coming next in the story, you can read George R.R. Martin's text that the series is based on — Fire & Blood — though the show has taken some liberties with the story, so it may not line up perfectly.
