A new “Game of Thrones” prequel about Aegon I Targaryen’s conquest of Westeros is being actively discussed at HBO,

As the project is in its very early stages, no writer is currently attached

though sources say that the search is underway as HBO is keen to move forward and get it into development.

Sources also say that there may be a feature component to the project

i.e. HBO and Warner Bros. would produce a feature film that would then lead into the potential series

though plans remain in flux at present.

The show would tell the story of how Aegon and his sister-wives, Visenya and Rhaenys,

used their army and their three dragons to conquer six of the seven kingdoms on Westeros with the exception of Dorne
