The Land of Zikola

Have you ever dealt with a currency different from paper money? Not coins, nor gold. Here, wealth takes a different form. You won't pay with money to acquire things; instead, you'll pay with your intelligence, with units of your mind. But beware, for wealth here has its limits. The bankrupt are not treated with disdain or insult as in your world. Instead, they face death.
Be cautious, for you are in the Land of Zikola.
