Variety has learned that HBO is considering a new GoT prequel, this one focused on Aegon I Targaryen’s initial conquest of Westeros. The project is in the very early stages, so there’s not even a writer attached yet, but there is energy and excitement on HBO’s side to move this series into development. What’s more, Variety has learned that there might even be a feature film element to this project.

The story would center on the tumultuous period (then again, when weren’t things tumultuous in Westeros?) when Aegon and his two sister-wives, Rhaenys and Visenya, conquered six of the seven kingdoms of Westeros with their armies and their three dragons. The lone standout was the southern kingdom of Dorne. This conquest led to Aegon becoming the very first king of Westeros and the first ruler to sit on the Iron Throne. It was Aegon who started it all, including all the palace intrigue and murder present in the Targaryen clan in House of the Dragon and the eventual, short-lived next ruler of all of Westeros, Daenerys Targaryen, whose journey we witness in Game of Thrones, which was set about 300 years after Aegon’s conquest.

There have been plenty of potential Game of Thrones spinoffs since the flagship series ended in 2019, with only House of the Dragon eventually making it to series. Game of Thrones remains one of the most popular television series of the modern era, and there’s little doubt that Warner Bros. Discovery won’t find a way to tell more stories from the rich, layered world that George R. R. Martin created. Perhaps the story of Aegon’s conquest of nearly all the kingdoms of Westeros will clear the internal hurdles and become not only the third series in the GoT universe but the first to be accompanied by a feature film.
