The bulk of the population is freeborn, also known as commoners. They may be farmers that work land owned by the lord, but merely pay rents on it or they may own the land in freehold. They may be craftsmen, or merchants or any of a myriad of occupations. Most characters will come from the freeborn class of society.
First roll to determine Freeborn origin.
Freeholders own their land, generally it is enough land to support one family, but occasionally they may have tenants. Since freeholds are granted by the crown they are fairly rare, but they are hereditary. A freeborn character of freeholder origin will have the farmer skill set plus perhaps one or more others from the townsman-villager skills list, they tend to be jacks-of-all-trades.
Freeborn farmers are the most common commoners. They receive the farmer skill set, on a roll of 1 on 1d10 they may also receive the townsman-villager skill set.
Townsmen are where the middle class comes from. From among their numbers come respected craftsmen, rich traders and other specialists like millers, bakers and brewers. There are also a variety of unskilled laborers and fairly destitute types among them, as well as the less savory prostitutes, actors and thieves. Towns offer the freeborn a chance at success, not a guarantee. Towns can be a small as an outlying village or as large as a bustling metropolis, the larger the town of origin, the greater variety in skill set.
Roll for town of origin size.
Village- the village is the standard proto-town. Most village inhabitants are actually farmers that live in the village and work fields around the village. There are, however, in villages skilled craftsmen that supply the villagers and the outlying farms with both necessary and luxury goods. A village will usually have a population of at least 100.
Town- Towns are, in many ways, like big villages. However fewer townsmen are farmers and more are specialists. Towns will have a population of 1000 or more. Towns will nearly always have a standing militia that doubles as a police force. Towns thrive on trade and are often based on a single trade that supports the bulk of their residents. Mining towns, market towns and fishing towns are quite common. Towns often have a charter that gives their citizens rights and exemptions that vex local nobles because the town falls officially outside of their domain.
City- Cities are what happens when a town hits it big. They may have been lucky enough to be on a major trade route or have an excellent natural harbor, perhaps they have a major temple or college; as often as not more than one of these things in combination with what would have made a successful town. They have hordes of specialists usually organized into guilds for quality control and price-setting. They have wealth and and a free population that makes your average noble look askance at them. Often they are ruled by a council of guilds, or an appointed lord-mayor. They nearly always have a royal charter. A city will have a population of 10,000 or more. A city will always have a militia, usually doubling as a police force.
Metropolis- A metropolis is like a city with a glandular condition, huge, sprawling and densely populated. A metropolis is likely to be an old, wildly successful city; a massive trading port, a national capitol, or a very sacred site. They are likely to have a multitude of temples, centers of learning, and centers of culture. A metropolis will have a population not less than 50,000 people, and nearly always have foreign ghettos. There are very few metropolises in the world. Oddly enough, though metropolises are really just huge cities, they are usually directly in fealty to either a king, a major temple, or a great noble; they do enjoy both great status and great privilege, usually the day to day governance of the metropolis is handled by appointed noble and freeborn officials in conjunction with elected magistrates and guild councils. A metropolis will often have a militia, always have a professional police force and quite regularly have actual full-time military units stationed there.
