Learn Valyrian history with this official Game Of Thrones video
Those unwilling to shell out the cash for a Game Of Thrones Blu-ray might not know that the series has apparently been producing mini-documentaries about Westeros as if the show were based on historical facts, not fantasy novels. Rather than acknowledge that this is all backstory created by author George R.R. Martin, this season one bonus feature is basically a Ken Burns-style documentary about the ancient Valyrian people (the line from which Daenerys Targaryen is descended).
