“House of the Dragon” Season 3 will premiere on HBO June 21.
Previously, it was known that the series would return in June. But on Monday, the network unveiled the fantasy series’ official return date. HBO also released a new teaser trailer for the upcoming season.
“You now have a power no man has ever wielded,” Daemon Targaryen (Matt Smith) says in this new teaser as his wife Rhaenyra (Emma D’Arcy) flies on the back of a dragon. “You will have an empire unassailable, Rhaenyra. And our children will rule it forever and a day.”
The teaser then cuts between the Targaryens and Alicent Hightower’s (Olivia Cooke) forces preparing for war. There are shots of sword fights, bloodied bodies and fire-breathing dragons.
“There will be no doubt who the gods have chosen to rule,” Rhaenyra says in the final moments of the teaser. Watch the video below
The second season of “House of the Dragon” ended on a cliffhanger. In an attempt to stop the war, Alicent secretly confronted Rhaenyra, admitted fault and asked that she and her children were spared. However, Rhaenyra insisted that she has to kill Aegon (Tom Glynn-Carney) — her half-brother and the main reason why Alicent started this rivalry in the first place — in order to end this war and secure her place on the throne. At the end of Season 2, Alicent seemed to agree with those terms and promised to keep the gate of King’s Landing open in three days.
“House of the Dragon” is a prequel to “Game of Thrones” as well as an adaptation of George R. R. Martin’s “Fire & Blood.” It is set roughly 200 years before the events of the main series and revolved around the Dance of the Dragons, a civil war that tore House Targaryen apart.
