Well, the world of Westeros...
Well at least the book version. HBO is not going to let George R.R. Martin's writer's block get in the way of completing the TV series. Of course, Martin has other distraction issues.
Can you really blame him? Writing is hard. Success can make further writing even harder to do (it is amazing what the need of a pay check can motivate you to achieve).
