Once the Warden receives this quest, a new location appears on the World Map, marked as Refugees. Travel to the location and fight the darkspawn, which consists of ten Hurlocks (including one Hurlock emissary) and three Genlocks. Once the fight is over (regardless of how many refugees survived) return to a Chantry representative for a reward.
