House of the Dragon's second season debuts with intricate opening title sequence ... Game of Thrones' prequel's sophomore slate includes eight episodes

House of the Dragon's second season debuted on HBO Sunday, as the first episode of the second season's eight-episode frame, titled A Son for a Son, hit the air.

The storyline of the second season starts at the end of the show's first season, in which Aemond (Ewan Mitchell) and his dragon Vhaegar slaughtered Lucerys (Elliot Grihault) - the son of Princess Rhaenyra (Eve Best) - and his dragon Arrax.

The deadly series of events ramp up the tension brewing between the Targaryens and Hightowers, eventually culminating in a civil war called The Dance of the Dragons.

The show's second season kicked off with a revised opening titles sequence that was noticeably different than the one broadcast in the show's first season.

The first season of House of the Dragon featured an animated opening that incorporated Old Valyria in a stone model, as it had been presided over by the late King Viserys Targaryen (Paddy Considine). It included red blood streaming through Valyria's streets, with symbolism alluding to the Targaryen leaders. 

Season two's opening focuses on a Bayeux Tapestry with references in the art to past events in the storyline.

The scene on the tapestry depicts bloodshed in Old Valyria, as well as Valyrians bonding to dragons. One sequence shows a man with a dagger in hand, as another man in knelt in front of a dragon while flanked in candles.

Viewers then saw an active volcano to signify the Doom of Valyria - an event in which the one-time Targaryen homeland saw people and dragons perish as every hill exploded in a fiery blaze.

Another sequence depicted Aegon the Conqueror on a quest to rule Westeros as he was flanked by sister-wives Visenya and Rhaenys as they rode dragons crossing the Narrow Sea.

Other notable happenings in the storyline seen forming on the tapestry consisted of events seen on the hit series Game of Thrones, which ran across eight seasons on HBO from 2011-2019.

One area referred to King Jaehaerys Targaryen (Michael Carter) at the head of the Great Council of Harrenhal, proclaiming Viserys as the realm's future leader, in addition to the commencement of the Dance of the Dragons.

Also seen in the tapestry is Rhaenyra Targaryen (Emma D'Arcy) and Alicent Hightower (Olivia Cooke) seen at a feast.

Aegon II Targaryen (Tom Glynn-Carney), the son of Alicent and half-brother of Rhaenyra, is depicted in the revised opening as the king of the Iron Throne, while Rhaenyra is named queen at the castle Dragonstone.

To conclude the opening credits is imagery depicting Lucerys Velaryon's (played by Elliot Grihault), death by the dragon Vhagar in the sky over Storm's End. 

Among the members of the ensemble cast slated to come back for the show's second season include Best, Matt Smith, who plays Prince Daemon Targaryen; Emma D'Arcy as Queen Rhaenyra Targaryen; Olivia Cooke, who plays Queen Alicent Hightower; Steve Toussaint as Lord Corlys 'The Sea Snake' Velaryon; and Rhys Ifans, who plays Ser Otto Hightower. 

The cast also features Fabien Frankel playing Ser Criston Cole, Matthew Needham portraying the role of Lord Varys Strong, Sonoya Mizuno playing Mysaria, Harry Collett as Jacaerys Velaryon, and Bethany Antonia in the role of Lady Baela Targaryen.

Phoebe Campbell plays the part of Lady Rhaena Targaryen, Phia Saban portrays Queen Helaena Targaryen and Jefferson Hall is in the role of Jason Lannister in the show's second season.
