It feels like every few weeks, we get yet another spinoff series announcement that will stretch the storylines and scope of the "Game of Thrones" universe. And joining a slate of upcoming projects that include the animated series "Nine Voyages", the untitled Jon Snow TV show starring Kit Harington, and a second season of "House of the Dragon" comes a planned prequel series centered on a certain Targaryen ruler.
Last week it was announced that HBO was developing a series based on Aegon the Conqueror, the founder and first king of the Targaryen dynasty who conquered the continent of Westeros and united the realm alongside his sister-wives Rhaenys and Visenya and their three dragons, Balerion, Vhagar, and Meraxes.
