Tal Nami System
the natives of this system require two foods in order to survive: the fruit of the egoa tree and the roots of the capabara plant. Unfortunately, they don't exist in the same region. So, in order to avoid their complete extinction, the Tal Nami natives developed an honorable and well-defined code of ethics that govern their trading. The underlying rule of any trade is that the other party should be getting the better deal.
