Among the criminals and outcasts of society who are part of the Night's Watch, some of them manage to climb the hierarchy and obtain important ranks on the Wall.
Among them, brothers of the Night's Watch are heroes. From veterans like Donal Noye and Othell Yarwyck who hold the front lines to experienced fighters commanding a larger force such as Qhorin Halfhand and Alliser Thorne, to new recruits like Grenn and Pypar who have adapted and proven themselves quickly. On the Wall, life is hard and the challenges are endless. You have to adapt or die.
