Nether Coin

Worse, Zagan brought this coin to the Avian camps, before the Korvian Plague swept through them. This nation was still poor and struggling to overcome their Orcish neighbors, but Zagan convinced them that money would be the solution. All over the world, Nether Coin was bought up until Zagan himself ran out of it. And then, the real chaos started.   Merchants started traveling, trying to sell the Nether Coin to other nations at high prices, only to find that they also had Nether Coin. By the time merchants from Udai made their way to Elone, everyone there already knew that, and trouble was starting to rise, as Dwarves and Elves thought the other had stolen it from them. Others realized they'd been scammed and were now bankrupt with worthless hunks of metal from Hell in their possession.   But Zagan's scheme was not finished. He had timed it perfectly, so that when the merchants all returned home, realizing their failure and losses, the coins would go off. What that meant is that they would release the "magical" property he'd mentioned: an enchanted smell so disgusting that anyone who came close to it would be unable to stop vomiting. It spread so far that entire cities were engulfed in the smell for a year before the coins were all thrown into the garbage dumps or the sea (many of which ended up in the dumps of Vitroveil). Meanwhile, the Devil had made off like a thief, wealthy beyond belief, and returned home triumphant.
