Ultimately, though, if we really want a somewhat different ending what we’re likely going to have to wait for is George R.R. Martin’s Winds of Winter and the subsequent A Song Of Ice And Fire novels, which will hopefully hit stores at some point.

That said, even George R.R. Martin has expressed that the show stuck close to his major ideas, at least when it came to how things wrapped up.
