Choose the henchmen or heroes that you wish to bring, then go into an explorable area anywhere in the far northern Shiverpeaks. Speak to one of the Norn by a Resurrection Shrine. If they ask for a fight, you must defeat them in order for this to work. Accept the offer they give you and you will receive the Norn Hunting Party effect. As long as you don't leave the area, you will gain Norn reputation each time you kill a monster.
