You receive a vision of a rooftop "somewhere close by", where a rare moss grows; in the vision, you know the moss is suitable for greatly enhancing the effects of certain types of potions. Now go and find that rooftop. Don't fall off. (Of course, rooftop runners *will* be taken for miscreants by the local City Watch....)
The Langdon Ballistics company has a short and muddled past of producing shoddy and cheap weapons. Stocks are made of orange plastic with black paint coverings, and metal components of the weapons they make are typically low cost alloys. Their most famous weapon is the L-12 Scatter Rifle, a fairly high power large bore shotgun. It is easily recognized by its orange stock and pronounced ammo clip.
