(CNN) HBO is now home to "House of the Dragon."

The cable network announced Tuesday it has ordered a "Game of Thrones" prequel from George R.R. Martin and Ryan Condal based on Martin's "Fire & Blood" series.

The show is set 300 years before the events of "Game of Thrones" and tells the story of the House of Targaryen, according to HBO.

Daenerys Targaryen, played by Emilia Clarke, was a major character in the mothership series, which ended earlier this year.

Condal will partner with Miguel Sapochnik and share showrunner duties on the new series.
