Our return to Westeros is around the corner.

Winter is coming? More like, the “Game of Thrones” prequel is coming.

This summer, audiences are returning to Westeros thanks to the buzzy new series "House of the Dragon." Set 200 years before the events of "Game of Thrones," the prequel dives into the history of Westeros, laying the groundwork for the eventual show. Think of the characters as Daenerys' distant ancestors.

The 10-episode series will have a different pair of showrunners than "Game of Thrones," and will be helmed by Ryan Condal and Miguel Sapochnik.

Like its predecessor, the new series will feature a carousel of characters, this time portrayed by Matt Smith (“Doctor Who”), Olivia Cooke (“Ready Player One”), Paddy Considine (“Informer”), Emma D’Arcy (“Truth Seekers”) and more.

While we know the new series will be based on George R.R. Martin’s “Fire & Blood,” the details of what we can expect are uncertain.
