First off, hey there! How you doing? I've been working on this fiction story that passes in a new world. Humans still exist, but they've been greatly reduced and the 2 greater factions are comprised of, well, entities of an elevated state, divided between, say, "good" and "bad". Now, humans only managed to organize themselves under one group well after the two factions were well established. As the weak earthlings attempt to settle in the new land, neither group can afford to pay them much attention, due to their current disputes and rivalry. So, humans founded a village, geographically in between the other two empires. There are other factors involved in their success in doing so, without any berating from the parties, but let's keep at that for now. --- Phew! Having said all that, I'm trying to create some sort of economy in this continent, by a commercial agreement of the parties, and operating under intermediation of the humans. In other words, the human city would act as a neutral zone for possible exchanges to occur between the rival factions, and humans themselves. PROBLEM IS - (and I know I'm not very savvy in history of civilizations and cultures and stuff, but) all I can find when I look back at both fictional and non-fictional examples of universal economy, is the need for freaking FOOD! The economy serves the purpose of providing us with out basic needs, mainly to avoid hunger. Other things are involved, obviously, such as shelter and etc. That wouldn't be an issue, if 66% of the individuals partaking in that economy weren't "ethereal creatures" with no real need to eat or sleep. I've been trying to think of other factors of need, that could serve as base for commerce between these parties but up until now I cannot find one in common What you guys think? Any suggestions or insight would be greatly appreciated!
