The Orc Khanate is primarily a nation that thrives on a barter system caring little for currency in the way that the humans do. The towns that do exist in the Orclands, deal with the nomad tribes and exchange food and exotic goods for furs and other hunted and foraged. The River Clans like the look of wealth and power and the feeling of superiority that those trappings bring, but ultimately they don’t care about the actual monetary value of these things. Rather, they worry about how good it makes them look in the strut.
The tinkers have a system of currency known as the Cog. The bronze silver and gold Cog system of currency is the normal token system used to measure wealth and rates of exchange for goods and services inside The Pit. The Goblin exchange rates fluctuate alarmingly quickly within The Pit and it is almost impossible to use outside due to the need to understand how much a cog is worth at any given time. Suffice to say that tinkers usually have their ears to the ground enough that they have a general idea of the relative worth.
When the demons showed the way to the Vale to the shaman they told them that rewards for souls and other items of interest would be paid for with what they called Shards. These small gem like crystals come directly from the demons beyond the mirror and it is unsure at this time what they are exactly.
Most of the currency in The Vale has become redundant, but with the change in the relative value of souls of all creature the value of soul ‘shards’ has become extreme, that can be used for powering all manner of things, and trading with the creatures of The Vale for powerful artifacts.
The source of power that comes from all races may have been started by the Demons, but is now accepted by all beings of great power, whatever they may be.
