-Old Bear Mormont, A Game of Thrones
At the northern edge of the Seven Kingdoms, there is the Wall. Built from massive blocks of ice and guarded by ancient, forgotten spells, it towers over 700 feet tall, forbidding entry to all who dwell beyond. A wall is only as strong as its defenders, and here, those defenders are the Night's Watch. In the Night's Watch, all men are brothers. Knights, lords, and the brothers of kings rub shoulders with slavers, murderers, and the scum of Westeros. Their task is grim and cold and thankless-no songs will ever be sung for them. Yet their vigilance is all that protects the southern lands from wildlings and the Others.
