In the middle ages what you owned was almost as important as who you were born to.
Bezants are used to buy outside resources, these can add depth and charcter to your medieval persona as well as add to your status in matters of precedence (They reflect work). A days work gets a bezant, as will other thingss to encourage growth of our society and rewards for merit.
Resources are also "taxed" at a rate of 5% per year to reflect medieval responsibilities.
