We have received reports that they are planning a major offensive against the Floating City. The ones you have slain so far have been advanced scouts for a larger army. Even more worrisome is that Orc Chieftain, Red Fang, has already advanced into the Harvesting Woods to the northeast. We believe he is intending to weaken our force before the assault. We have sent many assassins to get rid of him, but he has proven too strong, and too well guarded.
You must eliminate this threat to the city, or the city will be overrun."
Head down to Laksy's Anchor and take the road heading north. When the road forks and heads northwest, turn northeast into the Harvesting Woods. Head to the northeast corner in the back of the Woods. You will find Red Drill with three followers. If you miss killing him or can't find him don't worry, Red Drill re-spawns every 10 minutes. It is easier to kill the followers first as to minimize the number of monsters attacking you. Once you have killed Red Drill head back to Warehouse Keeper Sasha.
We are the Inquirers of the Sunset. The ones that seek light from the other side of the world."
