HBO's Game of Thrones prequel series House of the Dragon has cast Milly Alcock (The Gloaming) and Emily Carey (Get Even) in recurring roles for the upcoming show, according to Variety. The new spinoff is expected to debut sometime in 2022.

Alcock has been cast as "the young version of Princess Rhaenyra Targaryen, the king's first-born child, she is of pure Valyrian blood, and she is a dragonrider." Carey has been cast as "the young version of Alicent Hightower, the daughter of Otto Hightower, the Hand of the King, and the most comely woman in the Seven Kingdoms." Chances are, though, if you haven't seen or read Game of Thrones at any point over the last few decades (the novels, if you can believe, started in 1996), these names of places and characters won't mean much to you.

Fortunately, the show may prove to be a worthy entry to the franchise for newcomers. Greenlit last fall, this first 10-episode season is set 300 years before the events of the Game of Thrones series, meaning that most fan-favorite characters won't be appearing simply because they don't exist yet. The series is inspired by author George R.R. Martin's Fire & Blood, a sort of historical account of the world of Westeros, focusing on the rise of House Targaryen.
