Lastly, the above image spoofs House Stark's sigil (as seen on HBO posters http://fangirlshub.com/fgh/wp-content/uploads/2011/04/wallpaper-stark-1600-290x290.jpg ).
I enjoy both Thrones and Dragons so this neat to see. And after season 4 ends, I'll get my big fantasy fix by seeing the second film in theaters.
