A list of differences that can be found between the fifth season of the TV series and, roughly, A Feast for Crows and A Dance with Dragons, the fourth and fifth novels of the A Song of Ice and Fire book series. The two novels take place concurrently, with the fourth novel detailing events in the Seven Kingdoms, while the fifth novel follows events outside of them (at the Wall, Arya and Tyrion in the Free Cities, and Daenerys in Slaver's Bay). Originally, the fourth and fifth novel were going to be one very long novel, but Martin had to split them apart because it had grown too large. The TV series chose to simply intercut material from the two - which, in a sense, is recreating the original effect that George R.R. Martin intended.
