Here’s the next part of my Dark Sun conversion to Sword of Cepheus – the Merchant career. I’ve also included rules for trading.
I was originally just going to create a quick merchant class, but I got to thinking as I read about the dynastic merchant houses in the Wanderer’s Journal.

For Tyr to trade its precious iron for ceramic pots from Balic, a merchant must purchase the iron in Tyr, carry it to Balic, arrange an exchange, carry the pots back to Tyr, and sell them. The merchant makes a tidy profit at both ends of his journey—which is only fair, when you consider the risks involved in transporting such commodities.
One of my reasons for converting Dark Sun to the Cepheus Engine is to make use of all of those rules and subsystems that Cepheus/Traveller have used over the years. AD&D didn’t really have rules for trade and commerce (though the Dune Trader supplement has some basic rules), but the Cepheus Engine has a whole interplanetary trading subsystem that can be easily modified to work in a fantasy setting.
Setting the players up as traders gives them a nice excuse to set out across Athas: seeing new places, blazing trails to find new trade routes, and generally just getting into adventures.
I’ll put the merchant class in this post, and the trade rules in a separate post.
