In the Cliffs of Dohjok, just east of the quarry you'll find Nerashi, Lonai, Rojis, and Ahtok fighting off a small band of undead. After defeating them, proceed southeast to Beknur Harbor and simply follow the quest marker to clear off the undead. The undead are usually in groups of 4 Ancient Undeads with a mixture of different professions. Due to the proximity of mobs in the associated areas, be careful that you do not aggro more than you can handle.
