The North Remembers
“Game of Thrones” uses the phrase “The North Remembers” liberally, without importing its full meaning from the novels. In the books, this is the rallying cry for a group of dissidents who remain loyal to Robb Stark and his ideals even after he is rather forcibly removed from power. In fairness, there are a lot of warring factions in the “Ice and Fire” books, so it makes sense that not every political group could be included in the show. Sometimes offhand hints are good enough to get the job done.
