Enchiron

Economy

There exists, outside of any one country's jurisdiction, a merchant's guild. These are the people that make their fortunes off of international trade. The coin seen across Enchiron originates with them. Coin isn't accepted everywhere--especially in rural areas--but most city centers see the merchants often enough for it to be useful, or know someone who likes to trade with them. Coin isn't as valuable as raw material or labor, but it's gaining traction as a convenient shorthand.

Bartering is still preferred in most places.

Travel

As there's no reliable fast-travel in Enchiron, how long it takes to cross the country depends sorely on money, position, and location.

On foot, traveling from the coast of Eniya to the coast of Kimarel straight across Enchiron, it might take 8-10 months, depending on how you're getting around or through the Coronus mountains.
If you're riding in a horse-drawn caravan (or using a mount of similar skill), it takes half the time. This is the most common form of travel. If your horse isn't hauling anything, then that number drops to about 3 months.
There are a few species of megafauna that are more difficult to procure that can cover distance faster, in 1-2 months.
A tamed gryphon or dragon--species that can fly--can cross the continent in maybe a week, depending how hard you push it.
A flighted caelian--depending on the type of wings and tail feathers they have and their level of fitness--could take anywhere from a month to three.

Because travel is slower, a really generous guest culture has formed all across Enchiron. Guests are usually staying for at least a week, sometimes months.
