Dirt Money

Dirt Money was the currency of the civilization of Mars, before the disaster struck. Like all aspects of their civilisation, their currency is based on the plant cycle and therefore is made from some kind of special, rare dirt that therefore has a certain worth.

In Martian Dreams, the Avatar had to find some dirt money for the Xorinite Wisp in the Abandoned City in order to learn more about Mars and its civilisation.

Trivia

 * Dirt money can be found in the mines where the Avatar frees the two explorers from the cave-in in order to get access to Olympus.
