Dune Trader

Dune traders connect the far-flung cities and settlements of Athas, braving the wastes for the promise of coin. While most traders aspire to become master of a major trading house, all have to start small. They generally have no qualms about accompanying bands of roving adventurers, acting as negotiators, interpreters, and diplomats, appraising and bargaining for treasure and supplies. Those adventurers who accompany a young trader often form the core of a new trading house, are adopted into a trader's family, or live well as senior agents when the trader becomes successful.

A trader is often a master of intrigue and espionage, a subtle poisoner, and a natural fast-talker. They are excellent negotiators and schemers but tend to rely on companions or hired muscle in a fight. In most settlements and towns, traders and their party are allowed to sleep in their wagons in the marketplace for free. In larger cities, a trader may have to pay a fee for such a spot.
