Hartwin can also be found walking from the Wilderness Wall straight north into the Wilderness right above the Grand Exchange, presumably on a "scouting mission" for Captain Rovin. He disappears upon reaching level 5 wilderness. Sometimes Hartwin may be found randomly standing in the Grand Exchange. If you try to interact with him he says something along the lines of "Can't you see I'm rather busy, you should speak to my superior Captain Rovin." During the Battle of Lumbridge, he could be found wandering the crater. He still only referred the player to Captain Rovin.
