It links up with characters we've already met!
Last updated 19 hours ago
After the monumental, global success of TV series Game of Thrones, it's no wonder that bosses over at HBO have confirmed yet another spin-off series. The original show, featuring the likes of Kit Harington and Emilia Clarke, ran from 2011-2019 - and now major fans can look forward to A Knight of the Seven Kingdoms.
Based on the series of novels by George R. R. Martin, A Knight of the Seven Kingdoms will weave into the storylines we already know from both the original series, and also House of the Dragon, which will see its third season released in 2026.
Revealing that the brand new spin-off series will air on HBO in January 2026, show bosses took to social media to announce the news via New York Comic Con, using a well-known phrase from the original series as the caption: 'This Winter, Spring is Coming.'
Of course, fans went absolutely wild for the news, taking to the comments in their droves to share their excitement over the upcoming series. One wrote: 'Everybody wake up WINTER IS COMING 🐺,' while another added: 'OH YES THERE WILL BE MORE TARGARYENS AND THIS MAGNIFICENT STORY 🤩✨.' (sic)
Here's everything we know so far about the show...
When will A Knight of the Seven Kingdoms air?
The new series will begin on 18th January 2026.
How can I watch it?
The show will air on HBO Max, and subscribers to NOW TV will also have access to it.
What is it about?
Official press from Warner Bros. read: 'A century before the events of “Game of Thrones,” two unlikely heroes wandered Westeros… a young, naïve but courageous knight, Ser Duncan the Tall (Claffey), and his diminutive squire, Egg (Ansell).
'Set in an age when the Targaryen line still holds the Iron Throne, and the memory of the last dragon has not yet passed from living memory, great destinies, powerful foes, and dangerous exploits all await these improbable and incomparable friends.'
Is there a trailer?
The official teaser trailer dropped on Thursday 9th October, giving viewers the first look at Peter Claffey as Ser Duncan the Tal, and Dexter Sol Ansell as Prince Aegon "Egg" Targaryen.
The trailer was captioned with: 'A tall tale that became legend. The new #GameOfThrones series, #AKnightoftheSevenKingdoms, premieres January 18 on HBO Max'.
Check it out below:
Who will be in it?
So far, we know that Irish actor and former rugby player Peter Claffey will play Ser Duncan the Tall - aptly cast, as he is an impressive 6ft 5in, according to his IMDb profile! His prior work includes Bad Sisters and Wreck, with upcoming roles in Small Things Like These with Cillian Murphy and the third season of Vikings: Valhalla on Netflix.
We also know that his little sidekick, Prince Aegon "Egg" Targaryen, will be played by Dexter Sol Ansell, whose previous credits already include Emmerdale, The Midwich Cuckoos and The Hunger Games: The Ballad of Songbirds and Snakes among plenty of others - despite him being only 11-years-old.
How does it link with the original Game of Thrones series?
As with all Game of Thrones family trees, this one is also a little complicated - but we know that Prince Aegon, or "Egg", is the younger brother of Aemon Targaryen, who abdicated the throne to join the Night's Watch - AKA Maester Aemon, the blind elderly man who takes a shine to Samwell Tarly in the original series and passes away calling for his brother, Egg.
Without giving too much away, Prince Aegon becomes King Aegon V, succeeded by his son Jaehaerys, who in turn is succeeded by his own son, Aerys - also referred to in the original series as "The Mad King", who is the father of Daenerys Targaryen and her two brothers, Rhaegar and Viserys.
Viewers will remember Viserys as that rather annoying elder brother to Daenerys, who essentially sold her off to the Dothraki - but ended up meeting his rather nasty end at the hands of his sister's new husband, Karl Drogo.
Rhaegar ended up being the secret father of Jon Snow, whose mother was Lyanna Stark - sister of Ned Stark.
