HBO just unleashed the first Tyrion clip from the new season of Game of Thrones, along with a mess of stills presenting some "new" characters including Trystane Martell and Myrcella Baratheon (who was recently recast). Plus, you have to see this featurette on the history of the Targaryens and their dragons!
Now, here's the featurette we mentioned:
Valyria is where the Targaryens originally ruled, in the continent of Essos (as opposed to Westeros), and as you'll hear, where they found the dragons that helped them conquer the world. You may recognize the voice of the narrator as Harry Lloyd, better known as Daenerys' brother Viserys. He has excellent diction for having a mouth full of liquid gold, don't you think?
