According to Variety’s exclusive sources, HBO is actively talking about making another prequel series to Game of Thrones.

Since the project is just starting out, there isn’t a writer working on it yet. But the network wants to move forward with the show and get it ready for production.

Sources also said that there might be a feature film as part of the project. This would mean that HBO and Warner Bros. would make a feature film that would lead into the possible series, but plans are still in the air.

The plot of the prequel might be about how Aegon and his two sister-wives, Visenya and Rhaenys, used their army and three dragons to take over all but one of Westeros’s seven kingdoms, Dorne.

Aegon and Rhaenys were in a spin-off show called House of the Dragon. Tom Glynn-Carney (and also Ty Tennant) and Eve Best played them.

Aegon I was the first person to rule Westeros and sit on the Iron Throne. He also started the Targaryen Dynasty. About 300 years before the events of Game of Thrones, these things happened.

But this isn’t the first time HBO has worked on something. The news source said that, of all the projects that have been announced over the years, House of the Dragon is the only one that has moved forward so far.

Naomi Watts was in the abandoned pilot about the Long Night, which was the only other Game of Thrones project that had any footage shot so far. In the end, that project was canceled in 2019, the same day that House of the Dragon was given the go-ahead.
