As House of the Dragon continues to explore the rise and fall of House Targaryen, HBO is quietly developing another ambitious chapter within the Game of Thrones universe: Aegon’s Conquest. While still in early development, the project has already sparked considerable interest across U.S. entertainment media and among long-time fans of George R. R. Martin’s world.
At this stage, Aegon’s Conquest has not yet received an official series order, but its existence has been confirmed as part of HBO’s broader strategy to carefully expand the franchise.
The story that forged Westeros
Unlike House of the Dragon, which chronicles the internal collapse of Targaryen rule, Aegon’s Conquest would turn the clock back to the very beginning — the moment when power was first seized.
The proposed series centers on Aegon I Targaryen, who, alongside his sister-wives Visenya and Rhaenys, launched a brutal campaign to unite the Seven Kingdoms. With dragons as weapons of mass destruction and diplomacy backed by fire, Aegon’s conquest reshaped Westeros forever, laying the foundation for centuries of Targaryen rule.
Though frequently referenced in Game of Thrones lore, this era has never been fully dramatized on screen.
Creative direction and development status
The project is currently being written by Mattson Tomlin, a screenwriter known for his work on major studio properties. According to industry reports, HBO is still evaluating the scope of the project, weighing options that range from a limited event series to a multi-season epic, depending on the strength and scale of the final scripts.
Sources indicate that HBO is approaching the project with caution, prioritizing narrative depth, political complexity, and character psychology — lessons learned from both the successes and controversies surrounding the original Game of Thrones series.
What has not been announced
As of now, HBO has not confirmed:
-

Even the title Aegon’s Conquest is understood to be a working title, subject to change as development continues.
Why Hollywood is watching closely
In an era where legacy franchises dominate the streaming landscape, Aegon’s Conquest represents a crucial test for HBO: can the network expand one of television’s most influential worlds without diluting its impact?
With a story built on conquest, moral ambiguity, and the terrifying power of dragons, the series is widely viewed as one of the most thematically rich and visually ambitious prequels currently under consideration.
Final outlook
For now, Aegon’s Conquest remains a project in development rather than a confirmed release. Still, the historical weight of its story and HBO’s deliberate approach suggest that, if greenlit, the series could become a defining addition to the Game of Thrones canon.
