Qhorin Halfhand was a famous ranger of the Night's Watch and second-in-command at the Shadow Tower. Qhorin was good friends with Mance Rayder before he deserted the watch. On a search to discover Mance's intentions, Qhorin chooses Jon in his scouting party due to his warging abilities. When it's obvious they are doomed, he orders Jon to become a wildling spy and do anything they ask. Jon obeys, and kills Qhorin to prove himself to Rattleshirt and Mance.
