The dragons are coming. The Game of Thrones successor show, House of the Dragon, has begun production, the official Game of Thrones Twitter account said Monday, after a series of tweets that showed the fire emoji. The tweet included a photo of members of the production gathered at individual tables, each with computer screens.

The new show takes place before the events of Game of Thrones, the blockbuster fantasy series based on George R.R. Martin's novel series. It focuses on the Targaryens, an incestuous, dragon-riding royal family who eventually produces Daenerys Targaryen, a major character in Game of Thrones. It's inspired by the events of Martin's gigantic 2019 Targaryen history, Fire & Blood Vol. 1.
