Where the story of House of the Dragon left off: House Targaryen at war

House of the Dragon takes place approximately 200 years before the events of Game of Throneswhen the Targaryen Empire reigns supreme. After the death of King Viserys I Targaryen, the family that stood atop the Seven Kingdoms was suddenly thrown into chaos when a dispute over his heir created warring factions.

Season 2 of House of the Dragon faced strong criticism from fans and critics who claimed it focused too much on the key figures positioning themselves for the coming war. However, that positioning ensured that the series built up a lot of tension, which will now pay off.

During the final of House of the Dragon In season 2, fans saw Alicent Hightower dedicate herself to helping her former friend-turned-rival, Rhaenyra Targaryen, take King’s Landing in exchange for allowing her to leave unscathed with her daughter. Although that was an event of enormous importance, their intended truce is threatened by everything happening around them. Perhaps most strikingly, Aemond Targaryen’s rise to power as regent after betraying and nearly killing his own brother is a terrifying reality. The new ruler is a dragon rider who sits atop the monstrous ancient dragon Vhagar, making him a huge threat to anyone he chooses to threaten.

On a grounded level, season 2 of House of the Dragon has set things up perfectly for a massive clash known as The Battle of the Gullet. When Corlys Velaryon repaired his ship, renamed it after his late wife and left to join a blockade, he had no idea that a deal had been made to send a fearsome pirate to destroy him and his allies.

Another exciting part of where Season 2 left off is with a newly armed Daemon Targaryen. After spending the last few episodes in a haunted castle, he escaped, gathered a large group of men ready to fight, and pledged his loyalty to Rhaenyra. Now he’s about to wage war against her enemies, and it looks like he might take advantage of the opportunity.

One of the main storylines of the second season focused on the show’s titular creatures, the dragons. After allowing bastards to claim dragons with bloody results, Rhaenyra’s massive gamble paid off when she ended the season with three new riders claiming one each.

Why Season 3 of ‘House of the Dragon’ Could Be the Biggest Series Ever

After the criticism of House of the Dragon In Season 2, it looks like the action will ramp up in a big way in the coming episodes. In a series of interviews, showrunner Ryan Condal discussed the enormous stakes of what’s about to happen. While you’re talking to ComicBook.com in March 2025 he spoke about bringing important events from George RR Martin’s books to life.

“Season 2 is huge. Season 3 is bigger in many ways. There are, by my quick count onstage, four big events from the book that we have to adapt and realize in three dimensions this season. That’s really exciting from a scope and scale perspective, and I think that’s what the show does really well. The things we’re building are mind-boggling.”

More recently, in May 2026, Condal teased that House of the Dragon Season 3 starts with a bang. While you’re talking to Entertainment weekly, he described the premiere wilder from an execution perspective than anything in television history. He described it as “possibly the craziest television episode ever made.” The showrunner also told the outlet why it was so important to get the action right by making a powerful comparison.

“If we tried to tell this story without doing the Esophagus, it would be like trying to film Lord of the Rings without doing the Battle of Helm’s Deep. If we were going to do it, we had to do it right. And that meant dragons and ships and multiple points of conflict.”

Moreover, the star of the series, Emma D’Arcy, shared Entertainment weekly that viewers will finally see the action that the HBO series has been building towards since the very beginning. “The series opens at 60 miles per hour this time. We’re finally looking at a war that’s been building up for two seasons… I’m so impressed with Ryan and the team, because to really hold your nerve to stage a conflict that until now has been mostly interpersonal, interfamilial – and then (to) finally, in one grand gesture, allow that conflict to unleash itself on the Empire as a whole, I think is a very stylish plot.”
