The world of Westeros is getting bigger. Hot on the heels of the new show A Knight of the Seven Kingdoms, HBO and Warner Bros. are moving forward with another project set in the world George R.R. Martin created. This time, the story goes way back to the very beginning of the Targaryen rule. A new series based on Aegon’s Conquest is now in active development, and it brings together an interesting team. The writer behind the upcoming The Batman: Part II is working on the script, and he is doing it side by side with George R.R. Martin himself.
This is not just another show idea floating around. According to multiple reports, this project has been in the works for about two years. The writer, Mattson Tomlin, has been putting in the work. He recently shared photos on social media showing two notebooks completely filled with material for this very project . That shows serious progress. For fans who love the deep history of the Seven Kingdoms, this is the big one. It tells the story of how a single man and his three dragons changed everything.
The Dream Team Behind the New Prequel
Putting this show together requires someone who understands big, epic stories. Mattson Tomlin is that person. He is currently co-writing The Batman: Part II with director Matt Reeves. That movie is one of the most anticipated films in Hollywood. Tomlin also has experience with action and sci-fi, having worked on projects like Project Power and an animated Terminator series . He knows how to handle large-scale stories.
But the biggest news for fans is that he is not working alone. George R.R. Martin is directly involved in this project . The man who created this world is working with Tomlin on the scripts. This is important because it means the story will stay true to the books. Martin has been careful about which spinoffs he supports. His involvement here shows that Aegon’s Conquest is a priority. Tomlin confirmed that Martin is on board, which gives the project a lot of credibility . They are building this story from the ground up together, making sure the history and the characters feel right.
What is Aegon’s Conquest? A Look at the Story
So, what is this show actually about? The story takes place a long time before anything we have seen on screen. It is set about 100 years before House of the Dragon and roughly 300 years before the original Game of Thrones .
The plot is simple but huge. It follows Aegon Targaryen, also known as Aegon the Conqueror. Along with his two sister-wives, Rhaenys and Visenya, he decides to take over all of Westeros. They have three large dragons with them. In a short period of about two years, Aegon successfully conquers six of the seven kingdoms . Only Dorne holds out and remains independent. After his victory, he melts down the swords of his defeated enemies to forge the Iron Throne. This is the same throne everyone fought over in the original series.
This story also connects to a bigger mystery. Aegon had a prophecy. He believed a long winter would come from the North that would threaten all of humanity. He thought a Targaryen needed to be on the throne to stop it. This prophecy later became known as A Song of Ice and Fire . That is the same prophecy that drove events in Game of Thrones.
Could It Be a Movie or a TV Show? The Latest Updates
There is an interesting twist to how this story might be released. For a while, everyone thought it was just another TV series in development for HBO. But new information suggests it could be something much bigger.
According to The Hollywood Reporter, the project is being developed in two different ways at the same time . The HBO side is working on it as a possible drama series. But the Warner Bros. film team is also looking at it. They want to turn it into a major motion picture. The goal is to make it a “mammoth Dune-sized feature film” . This means they want it to be a big, cinematic event that people watch in theaters.
It is not clear yet which path they will take. It could end up as a series, a movie, or maybe even both. For now, it is being developed in both directions until a final decision is made. The fact that they are thinking about a theatrical release shows how confident they are in this story.
Where Does It Fit in the Timeline?
With so many Game of Thrones shows now available or on the way, it helps to know where this one fits.
Right now, ** A Knight of the Seven Kingdoms ** is currently airing on HBO. That show is set about 100 years before the original series. It follows the adventures of Ser Duncan the Tall and a young Egg, who later becomes King Aegon V Targaryen .
Later this year, in June 2026, ** House of the Dragon season 3** will premiere . That show is set about 200 years before the original series and covers the Targaryen civil war known as the Dance of the Dragons.
Aegon’s Conquest goes back even further. It takes place roughly 300 years before Game of Thrones. It shows how the Targaryens first came to power. This makes it the earliest point in the timeline that HBO has explored in live-action so far. It is the origin story for the entire dynasty.
Fan Excitement and Casting Rumors
Even though the show is still early in development, fans are already talking about it. One of the biggest topics is who should play Aegon the Conqueror. Many fans have started campaigning for actor Henry Cavill to take the role . He has experience with fantasy worlds, having starred in The Witcher. Fans think he has the right look and presence to play the legendary warrior king.
There has been no official casting news yet. The project is still in the writing phase. But the fan support for Cavill shows how much excitement there is for this story. People want to see the beginning of the Targaryen empire on screen.
Mattson Tomlin has been keeping fans updated in small ways. When a fan asked him on social media how much of the script he had written, his answer was simple: “LOTS” . That kind of energy is good to hear. It means the creative team is passionate about getting this story right.

What This Means for the Future of the Franchise
HBO is clearly not slowing down with Game of Thrones. With House of the Dragon running strong and A Knight of the Seven Kingdoms now on air, they are building a whole universe. Adding Aegon’s Conquest to the mix gives them a story that covers the very foundation of the world.
This project is different from others they have tried. In the past, they developed spinoffs like one about the adventures of a young Jon Snow, but that idea was eventually shelved . They also had a pilot called Bloodmoon that cost millions but was never picked up . Aegon’s Conquest feels more solid. With George R.R. Martin personally involved and a hot writer like Tomlin attached, this one has a much better chance of actually making it to the screen.
The story also has a clear ending. Aegon’s conquest is a complete tale. He arrived, he fought, he won, and he built the throne. That structure might work very well as a limited series or as a single epic movie.
For now, fans will have to be patient. The scripts are being written, but no official release date exists. The project has not even received a formal series order from HBO yet . But the progress is real. Tomlin has filled two notebooks. Martin is giving his input. The story is moving forward.
While we wait, there is plenty to watch. A Knight of the Seven Kingdoms is releasing new episodes now. House of the Dragon season 3 is coming in June. And behind the scenes, the story of the Conqueror is slowly being built.
