transportation system - Mages have developed a complicated 'door' system which leads from one town to the next through teleportation. But if needed people can travel by horse or a guarded carriage. Cars and other vehicles have become almost useless due to the fact without gas they can't really move. Even shadow controlled cars can only sit there due to the fact they have run out of fuel but don't touch them or run the chance of becoming infected.
Communication system - Naturally after all this cellphones would be completely useless now. People will often get a job taking mail throughout town or paid to go from town to town with bags of letters.
Bounty system - If you bring back parts of anything that contain the presence that a shadow controlled it you can be rewarded. The stronger the presence of the shadow the more you will be rewarded. This basically means the stronger the shadow you kill the more money you will get. You can get them appraised by a mage that can be found in almost every town. It's a system set up by the first city established.
Mercenary system - A system that usually made by the town. They will often pay highly for a group of people to take on a powerful shadow or many smaller shadows. This can often be very dangerous,
Mercenary school - Set up in the first city established. It trains young abandoned kids to become stronger. It goes from first grade to college and provides battle strategy and real combat. It has mixed views on it but in the end its there to stay (you could literally never be in it or constantly be in it, up to you really)
Market system - Every day people will line the streets of a selected part of their province and offer goods and services. It's thought very stupid to accept anything at asking price so people usually haggle with whoever their buying it from. They also often accept anything you collect from your travels but you better be good with haggling if you want a decent deal.
Money system - This system is very confusing at first due to the collapse of the money systems. Most towns and cities have a different form of money system but it all deals with coins now. The money system is based off the 'trenny silver coin'. If used right a person could live 3 days off a single coin.
trenny gold coin = 500% a Trenny silver coin.
Trenny silver coin = the base.
Trenny copper coin = 10% a Trenny silver coin.
Elvic silver coin = 75% a Trenny silver coin.
Elvic copper coin = 8% a Trenny silver coin.
Alph gold coin = 200% a Trenny silver coin.
Alph gold coin = 40% a Trenny silver coin.
Alph copper coin = 4% a Trenny silver coin.
These are the most commonly used forms of money but they're much more and the value of them depends on how rich the town or city is.
Government - there is no true government system. Whoever runs a town or city is basically the leader. What they say is law and they have absolute power. This being said many richer cities will keep an eye on the smaller ones and assassinate a corrupt leader to keep things running smoothly.
