Once again, this plays with this world’s timeline a little bit. Such is a demigod’s lot in life.
Nagus Sterling, the Lord of Longing, was restless as he watched the people below. They were so… inefficient. So random. And so wasteful! They needed a little guidance, the kind he was uniquely qualified to give. He knew where it would lead eventually, of course (he was a god after all), but it was all a part of the game.
Nagus Sterling’s Gift to Civilization is Commerce, money and the knowledge of its use in buying, selling, and the whole field of exchange. Thanks to Etterskell’s influence the world was blessed with multiple currencies scattered throughout the realm, different states, different races, even different cities claimed their own. This created confusion. It would be so much simpler to generate a single system, but confusion would be so much easier to exploit.
