Season 5 New Character & Locations

HBO has just released another behind-the-scenes video, this time talking about the new characters and locations in season 5 of Game of Thrones.  It's a bit odd to get a video talking about the new characters and locations half way through the season.  Nonetheless its still nice to get inside the heads of the creators, and hear their explanations and thoughts on each piece.  And the video shows us a few glimpses of a some scenes we have not seen yet - mainly on the Dornish side.  

The video focuses heavily on the new characters in Dorne: Doran Martell, Areo Hotah, and the Sand Snakes.  While also touching on one of the seasons new locations found in Dorne, the Water Gardens.  The video briefly covers the High Sparrow, and the House of Black and White. 

What did you think of this new behind-the-scenes video?  And which of these characters or locations are you most excited about seeing more of?
