HOUSE OF THE DRAGON is the name of the new HBO spin off from Game of Thrones thats been picked up for a full 10 episodes aka one season. Its about the beginnings of the House Targaryen and their dragons. So that’s totally awesome!

Sadly they canceled the other spin off show THE LONG NIGHT about the Age of Heroes. It would have been nice to see the origins of the Starks. Oh well. Perhaps another time.
