HBO is further expanding the Game of Thrones universe with a new spin-off focusing on the legendary figure who unified the disparate kingdoms of Westeros under one rule, Aegon the Conqueror. This series, set to delve into Aegon’s Conquest (and presumably, the Targaryen’s decision to flee from Valyria, will serve as a direct prequel to House of the Dragon, providing a detailed look at the Targaryen’s bloody and brutal conquest of the continent. With Mattson Tomlin, known for his work on The Batman and its sequel, at the helm, expectations are high for a compelling addition to the epic fantasy saga.
Aegon’s Conquest is a pivotal event in Westeros’ history, marking the rise of the dominance of what would later become known as the House of the Dragon. Alongside his sister-wives Rhaenys and Visenya, Aegon launched an invasion that would change the face of the continent.
With the power of their dragons, they were able to unify six of the Seven Kingdoms, leaving Dorne as the only region to maintain its independence initially. This historic campaign led to the creation of the Iron Throne, a symbol of the Targaryen dynasty’s unyielding rule over Westeros.
According to The Hollywood Reporter, the new series aims to capture the essence of George R.R. Martin’s richly detailed world, taking a “back to basics” approach to the complex lore of A Song of Ice and Fire. This focus on one of the most iconic figures in Westerosi history is an opportunity to explore the motivations, strategies, and consequences of Aegon’s campaign. Fans can expect to see the tactical use of dragons in an all-out war, the political machinations that accompanied the Targaryen invasion, and the cultural impact of unification under a single ruler.
Tomlin’s involvement in the project is particularly exciting for fans, given his track record of engaging storytelling and dynamic character development. Tomlin’s uncredited work on The Batman showcased his ability to delve into dark themes and complex protagonists, skills that will undoubtedly benefit the portrayal of Aegon the Conqueror.
With House of the Dragon set to return for its second season later this summer, the hype for more Targaryen tales is at an all-time high.

While HBO has greenlit other spin-offs, such as A Knight of the Seven Kingdoms: The Hedge Knight, the network’s commitment to exploring different facets of Westeros is still suspect. The success of House of the Dragon has proven there remains a vast appetite for stories set in Martin’s universe, and Aegon’s Conquest promises to be a thrilling addition to the multi-awarded franchise. But we have to remember that HBO has canceled shows before or turned them into animated projects.
Nevertheless, by focusing on the conqueror himself and the impact of his actions, HBO is set to provide audiences with a deeper understanding of the Targaryen legacy and the events of the Game of Thrones saga.
As the anticipation builds, the promise of returning to a world of dragons, intrigue, and, of course, epic battles ensures that the legacy of Westeros will continue to captivate audiences around the globe.
Besides, who wouldn’t want to see Balerion the Black Dread, the absolute unit that he is, wreaking havoc on all of Westeros?
