Since Game of Thrones’ grand finale in May 2019, several spinoffs set in the world of A Song of Ice and Fire have been reported to be in development. Only two have seen the light of day so far: House of the Dragon and A Knight of the Seven Kingdoms.
HBO canceled a Naomi Watts-starrer series on the first Long Night, titled Bloodmoon, even after filming a $30 million pilot. An untitled Jon Snow sequel and another show called Flea Bottom, based on the King’s Landing slum, were also shelved.
At CinemaCon 2026, Warner Bros. confirmed that a Game of Thrones movie is officially happening, currently titled Aegon’s Conquest. The story of Aegon I Targaryen and his sister-wives, Visenya and Rhaenys, conquering Westeros on their ginormous dragons, has been something fans have long wanted to see.
Some other A Song of Ice and Fire TV spinoffs that are reportedly still in production include the animated Nine Voyages, following the adventures of Corlys Velaryon, Ten Thousand Ships, following Princess Nymeria leading the Rhoynars to Dorne after her home, Rhoyne, was conquered by the Valyrian Freehold, and The Golden Empire, an animated show focused on the ancient empire of Yi Ti in Essos.
While these include some of the lore the Game of Thrones fandom would love to see if they ever get made, there are many others that viewers keep talking about online, in the hope that the discourse gains enough traction to capture the attention of Warner Bros. and HBO.
With House of the Dragon’s return to HBO, here are 10 Game of Thrones spinoff ideas that fans still keep talking about on the internet and would definitely spend their money to see.
- Robert’s Rebellion
- The Rains of Castamere — History of House Lannister
- Arya Stark’s adventure west of Westeros
- The Doom of Valyria
- The invasion of the Andals
- Night’s Watch Rangers’ missions beyond the Wall
- Gerion Lannister’s expedition to Valyria
- The original Long Night and the history of the Night’s Watch
- Tale of Lord Bloodraven
- Stories of Essos
Robert’s Rebellion
The war that toppled the Targaryen dynasty and put Robert Baratheon on the Iron Throne is arguably the most consequential event in modern Westerosi history. Yet, we have only ever seen its aftermath.
After Aegon’s Conquest, Robert’s Rebellion has been one of the most sought-after Game of Thrones spinoffs, meant to focus on the political turmoils leading up to the insurrection and the war Robert waged against Rhaegar Targaryen for “eloping” with his betrothed, Lyanna Stark.
The series should ideally start at, or sometime before, the Tourney at Harrenhal, where Rhaegar caused quite the scandal by crowning Lyanna, who was already promised to Robert at the time, the Queen of Love and Beauty, instead of his wife and the mother of his children, Elia Martell.
Even though we already know the truth, it would be interesting to see the doomed yet catastrophic love story between Rhaegar and Lyanna from a different perspective, along with the immediate and quite bloody consequences of their romance.
Fans would expect to see the burning of Rickard and Brandon Stark, Ned Stark’s rise as a leader and his friendship with Robert, Aerys II Targaryen’s gradual decline into the Mad King, and the Lannisters wiggling their way further up amid the chaos of it all. We may even see a baby Daenerys Targaryen.
However, the main attraction would be the culminating Battle of the Trident, where Robert’s warhammer crushed the breastplate of Rhaegar’s armor, killing the prince and clearing the way to the Iron Throne.
The Rains of Castamere — History of House Lannister
Long before Tywin was the Hand of the King, Cersei sat on the Iron Throne, and the Lannisters started running out of their precious yellow metal, the House of the Lion was building their legend through cunning, cruelty, and a questionable amount of gold.
A prestige drama tracing the rise of the Lannister dynasty — from Lann the Clever swindling the Casterlys out of their own rock, through the violent suppression of House Reyne immortalized in the song “The Rains of Castamere” — would be quite a Shakespearean power study.
The extermination of the Reynes and Tarbecks by a young Tywin Lannister could serve as the centerpiece: a cold, methodical act of warfare that defines the man he becomes when we meet him in Game of Thrones.
If the showrunners feel benevolent, we may get Jaime, Cersei, and Tyrion’s childhoods, more on Cersei’s prophecy from Maggy the Frog, and the contrast between Tyrion’s early relationship with his brother and his sister.
Arya Stark’s adventure west of Westeros
Given how the ending of Game of Thrones disappointed many, fans aren’t too keen about any potential sequel spinoffs, except for Arya Stark’s westward journey. She set sail to find what’s beyond the edge of the known map of Westeros, and we would like to know what she finds out.
A seafaring adventure series following Arya as she discovers lands and civilizations no Westerosi has ever documented would be the franchise's opportunity to go somewhere genuinely new.
The creators can test Arya’s time- and war-hardened combat skills against scary sea monsters, rogue pirate ships, or peoples of a previously unknown civilization who think of her as an enemy.
And who wouldn’t like to see Maisie Williams return to the world of Game of Thrones? If we are lucky, we could see brief cameos from Sophie Turner’s Sansa Stark as well, in flashbacks or after Arya returns from her adventures.
In January, a report from The Hollywood Reporter claimed Arya could return in the Jon Snow sequel should it ever happen, with writer Quoc Dang Tran tapped to develop a potential story. We haven’t heard anything else on that subject since then, but it’s apparently in the cards.
The Doom of Valyria (also known as "the Doom" or the "Doom of the Valyrian Freehold") was a catastrophic, sudden event that took place approximately 400 years before the War of the Five Kings, conventionally dated to 102 BC or 114 BC. It destroyed the city of Old Valyria and… pic.twitter.com/fe0i9rCeer

The Doom of Valyria
Long before the rise of the Targaryens in Westeros, Valyria on Essos was the greatest civilization in the known world. With dragons, wealth, and magic in abundance, their power seemed unstoppable.
Aegon the Conqueror’s ancestor, Aenar Targaryen, managed to escape the devastating cataclysm that later came to be known as the Doom of Valyria, thanks to his daughter, Daenys the Dreamer’s visions. He became the first-ever Targaryen lord to drop anchor at Dragonstone, changing the future of Westeros forever.
A little over a decade later, the fury of the Fourteen Flames laid waste to Valyria, filling the air with smoke and ash, boiling the waters, killing everyone — even the dragons — and fragmenting the peninsula itself. The water around the land came to be known as the raging, bubbling Smoking Sea, and gave birth to dozens of nightmare-ish legends.
As a Game of Thrones spinoff, Doom of Valyria has the potential to be one of the most visually spectacular and tragic stories told on TV. There would also be a whole new set of dragons for fans to fawn over.
What intrigues fans about it is the mystery surrounding the cause of the deadly catastrophe. It is known that the 14 volcanoes simultaneously erupted, which many believe is too much of a coincidence to be true.
Some septons within the ASOIAF universe believe that the polytheistic Valyrians’ “sins” raised hell on their land. Other maesters have theorized that the magic controlling the Fourteen Flames either faltered on a massive scale or was sabotaged because of infighting. One theory suggests that the Valyrians dug too deep, à la the Mines of Moria in The Lord of the Rings, and destabilized both the earth beneath and the magic that kept the fire under control.
Another theory, one that many fans would like to see explored in a potential spinoff, is that the Faceless Men of Braavos triggered the calamity. The famous assassin order that Arya Stark joined was originally formed by enslaved people forced to work in treacherous conditions under the mines of the Fourteen Flames. It is widely speculated that they killed the blood mages and sabotaged the spells, thereby causing the Doom.
The invasion of the Andals
Some accounts say that the Andals crossed the Narrow Sea to Westeros 6,000 years before the events of Game of Thrones, some say it was 4,000, and some others claim it was nearly 8,000. ASOIAF lore is deliberately vague and contradictory about dates and incidents of the ancient past, as they often are in the real world. But the nature and aftermath of their arrival are unanimously agreed upon.
Led by Hugor of the Hill, the Andals set sail for Westeros from the hills of Andalos in Essos, and the thousands of years of peace that prevailed in the land since the Pact between the First Men and the Children of the Forest went for a toss.
They brought with them steel weapons and the Faith of the Seven to settle in Westeros, allegedly leaving their homelands under the pressure of the then-expanding Valyrian Freehold. Their migration soon turned into a conquest, sparking generations of brutal warfare against the First Men, who had ruled Westeros for centuries by then.
A grimdark series set during this era could explore the conflict from multiple perspectives, showing both the desperate ambition of the Andals and the pushback from First Men kings, as well as their allyship and enmity with Houses we know from the original show, such as the Arryns and Lannisters.
Then, of course, there would be the Starks of Winterfell, who not only repelled every Andal attempt on the North and held the line at the Neck, but also sailed east and raided Andalos in retaliation.
Beyond the warfare, the series could delve into the gradual blending of cultures that eventually gave rise to the Westeros seen in Game of Thrones.
Night’s Watch Rangers’ missions beyond the Wall
Could a Game of Thrones spinoff that doesn’t have kings, dragons, or wars even work?
Some fans believe it would. On a Reddit thread that discussed potential GoT spinoff ideas, one fan commented that they’d like to see a “True Detective type cop show of Rangers going beyond the Wall, solving missing person cases where brothers have disappeared beyond the wall over the years.”
The idea got several upvotes, and another fan even suggested that it should feature appearances from a young Mance Rayder, the leader of the Free Folk wildlings, and Craster, the incestuous man who bred his own daughters and gave up his infant sons to the Night King in exchange for protection.
The show could offer procedural stories on the countless mysteries that might be hiding in the snow-clad forests and wastelands. The North itself would become a character, with endless snowfields, eerie forests, and abandoned ruins creating a constant sense of dread.
Most importantly, it would allow the franchise to explore corners of George R.R. Martin’s world that have only been hinted at. Who knows? Maybe there are things out there more terrifying than the Night King.
It could be one of the most distinctive entries in the Game of Thrones universe, adding a psychological and supernatural horror flavor to the fantasy world, but it may not sit well with fans who prefer deep GoT tie-ins in their GoT spinoffs.
Gerion Lannister’s expedition to Valyria
This one could get tricky, as it would realistically require appearances from known Lannister characters, albeit in their younger versions. But that does not mean it is not a cool idea for a spinoff.
Gerion Lannister was Tywin’s youngest brother. The two always had a tumultuous relationship, with Tywin’s shadow eclipsing all of his siblings, while Gerion, aware of the pointlessness of competing, made jokes about his brother’s politics. However, Tyrion and Jaime often referred to him as their “favorite” uncle.
Less than a decade after Robert’s Rebellion, but before the events of Game of Thrones, Gerion set sail on the Laughing Lion ship on a quest to find House Lannister’s ancestral Valyrian steel greatsword Brightroar that was lost somewhere in Essos.
He was never seen again. Tywin’s search party later brought news that he had last stopped at Volantis to acquire enslaved people to replace the members of his crew who fled out of fear of the Smoking Sea.
The series would begin as a classic maritime adventure, with Gerion assembling his crew, all drawn by the promise of finding the lost treasures of Valyria. But the further east they travel and the closer they get to the ruins, the myths of Lovecraftian demons and blood magic gone wrong begin to become real, tangible threats.
A fan on Reddit suggested that the show could be a “slow burn, 10-episode horror miniseries akin to The Terror and The Color from Outer Space.”
The show could also follow two timelines. One would be set in the present, following Gerion. The other would be set centuries earlier, following Tommen II Lannister, who also went on a similar odyssey with the intention of plundering what remained of Valyria. He disappeared, and so did Brightroar. His fleet never returned, nor Tommen, nor Brightroar.
The parallel timelines of the entwined fates of two Lannisters centuries apart, who became nothing more than footnotes in Westeros history despite their high goals, could certainly make for a fun show.
The original Long Night and the history of the Night’s Watch
The premiere of House of the Dragon season 2 posed a very interesting question.
“Do you think my ancestors built a 700-ft wall of ice to keep out snow and savages?” Cregan Stark asks Prince Jacaerys Velaryon. “What does it keep out?” Jace responds, to which the Lord of Winterfell says, “Death.”
We know that it is likely meant to refer to the Night King and his legion of White Walkers. What we don’t know, because the show never truly told us, is what the guy’s goal was.
Sure, he was terrifying for a bit, managed to bag a dragon for himself, and nearly ran through the defenses of Winterfell with his dead army. He wanted to cause the Endless Night after erasing all of humankind and killing Bran, who, as the Three-Eyed Raven, is the memory of all time. It still doesn’t explain why Night King wants to do that.
Fans, as always, have shared their theories since he was introduced, and have continued to do so since the final season aired.
“He's a weapon created by Children of the Forest to eradicate mankind,” one fan wrote. “It doesn’t have a purpose… He’s just a malfunctioning magic beast that destroys everything in his wake until he and White Walkers race are the only ones left.”
Another fan said that it wasn’t a “malfunction” but rather the very task he was created for: “Some people are saying he was programmed to kill all humans since the children of the forest had to defend against the men who invaded Westeros. So he might have been on some kind of autopilot, killing every human being.”
A series on the original Long Night, when the sun disappeared for an entire generation and froze kingdom after kingdom to death, could answer some (or all) of the questions we have about the Night King and the White Walkers. It would also allow the perfect opportunity to introduce legendary ASOIAF figures like Bran the Builder, the Stark ancestor who built the Ice Wall, and the Last Hero, who journeyed into the frozen north to seek the aid of the Children of the Forest and helped defeat the Walkers.
The Wall was erected right after humanity’s hard-won victory, with the Starks sending one in every ten family members to help fortify the gargantuan structure. Cregan Stark called this oath a more important one than any other.
This is the foundational story of Westeros, the event that shaped every kingdom, every legend, and every warning passed down through generations, and therefore is definitely worth telling on an epic scale.
Tale of Lord Bloodraven
Brynden Rivers, a.k.a. the Bloodraven, is a fan-favorite character among those who follow the deeper lore of ASOIAF. His story should be one of the easiest to explore as a spinoff, as he is connected to all three existing shows in the universe.
A character steeped in myth and mystery, we have already seen him play a significant role in Game of Thrones. We also caught a glimpse of him in House of the Dragon when Daemon was having his vision.
Brynden Rivers was a legitimized bastard son of King Aegon IV Targaryen, who eventually picked up the mantle of the Three-Eyed Raven, the greenseer who lived with the Children of the Forest and mentored Bran Stark to take on his role.
Many years before that, he fought in the Blackfyre Rebellions and served as the Hand of the King to Maekar I Targaryen, whom we know from A Knight of the Seven Kingdoms. After Maekar’s death, Aegon V (Egg) sent him to the Night’s Watch for what he deemed a dishonorable act, where he rose to the position of Lord Commander and disappeared while ranging beyond the Wall.
He carried the Dark Sister as a Targaryen, the one we see Daemon wield in House of the Dragon, and it is believed he took it with him when he vanished.
But more importantly, he was quite the mystical figure, both in King’s Landing and at the Wall, known for doing all sorts of spells and spying, which earned him the name Lord Bloodraven and the song, A Thousand Eyes and One.
There are a bunch of theories about the character, including one that says he might have the ability to manipulate events and engineered the Targaryen bloodline to create The Prince That Was Promised.
All things considered, Bloodraven’s tale would have the perfect balance of political intrigue in the early part of his life, giving way to something strange and supernatural, and both intricately tied to Westeros’ future as we know it.
The Five Forts in Essos serve as the border between the Golden Empire of Yi Ti and the Grey Waste. Each massive fortress can house 10,000 men

Stories of Essos
Despite the First Men, the Andals, and the Targaryens all coming over from Essos, the land itself remains one of the most diverse yet least explored parts of Martin’s world. One on Yi Ti is likely in the works. Still, a new tie-in spinoff set in Essos could adopt an anthology format, with each episode focusing on a different region, culture, historical event, or time period.
The possibilities are nearly endless: the political rivalries of the Free Cities featuring wealthy families, assassins, and sellswords, the shadow magic and old prophecies of Asshai, imperial drama of Yi Ti, or adventures across the Jade Sea.
Established characters, such as Corlys Velaryon, could make occasional cameos to keep casual fans interested.
By stepping away from the dragons and dynasties of Westeros, the series could introduce audiences to a new set of storylines that do not all end in Bran the Broken sitting on the throne.
