Down on the docks, right next to the train tunnel #2 boss_baby684 Mar 25 @ 3:41pm ok this is helpfull #3 Axeface Mar 25 @ 4:33pm Thanks all, yeh found it. After going to the docks and finding the entrance you need to head to the mayors office to get a permit.

To be able to start this quest, you must obtain a Sewer Permit. Head towards the Sewer Entrance, found in the harbour (Marked A on the map below), and speak to the worker. He will tell you that you need the aforementioned permit. From here, make your way over to the Mayor's Office (Marked B on the map below).
