To start this quest you need to find a Ofier diagram that is untranslated. Take the diagram to the Ofierian Salesman near the Upper Mill signpost. If you ask him about the diagram, he explains that it is part of a full set and the other diagrams were stolen. He gives you a clue by telling you where he was attacked and the diagrams were stolen. Ride Roach to the scene of the attack and investigate.
