He is a ranger of the Night's Watch.
After meeting the force led by Lord Commander Jeor Mormont at the Fist of the First Men, Qhorin Halfhand selects Stonesnake, Harker, and Borba for a scouting party to ambush a group of wildling lookouts. They are joined by Jon Snow. They locate and surprise the lookouts, killing all but one of them. Jon is left to execute the wildling survivor. Jon does not return and they return for him. They pick up his tracks but are ambushed by wildlings. Harker, Stonesnake and Borba are killed while Qhorin is captured. Jon had spared the captive and she leads him into a similar ambush. Qhorin seizes the opportunity to insert Jon as an infiltrator in the wildling ranks by berating him for the deaths of the others publicly.
