Zenku is a thief who robs a Market Merchant. He appears randomly together with the Market Merchant. If they are both there, then Ling will most likely not be there. Zenku will steal from the Market Merchant and run away towards the cliffs, prompting a nearby Canthan Guard to give chase. Eventually they end up at the entrance into Nahpui Quarter and disappear. They appear to serve no other purpose than to show the way to Nahpui Quarter.
