The Arrnilioh was the currency of the Drijokenleein, and later the Keaarglrs and the Eniamos when the three races united. The first Arrniliohs were made from a kind of shiny mineral. The arrnilioh stones made way for better forms of money, but the name Arrnilioh stuck, and almost all incarnations of Drijoken money were various kinds of minerals.
When the Drijokenleein befriended the other species, money made from plant products proved to be most convenient. However, the official currency was still called the Arrnilioh, and valuable rocks and gems were kept for decoration and badges of prestige.
