Gnome traders are mostly roving travelers that seek to sell gnomish handiwork (such as clockwork machines), magical items (such as wands and scrolls), and/or historical items of importance (such as weapons or trinkets). Typically, a trader will set up in a town for no more than two weeks, although, if the town is rich in history, the trader may stay longer, or even take up permanent residence. While traveling, a trader will hire adventurers or mercenaries to protect his goods and more successful ones will have clockwork constructs. While on the move, a trader will not shy away from a sale on the road.
