Birthright: A New World
A domain consists of provinces, holdings, resources, and assets:
Provinces represent political divisions of land and the people living in them. Each province has a level that roughly describes its population and development. For example, a level 0 province would be a thinly settled frontier province, level 5 would be the area around a mid-sized city, and level 10 would be a major metropolis. Provinces usually earn money for their regent in the form of taxes.
Holdings represent centres of power within a province. There are four types of holdings> Law (legal/military power), Temple (religious), Guild (economic), and Source (magical). Like provinces, holdings have levels, which describe their degree of influence within the province. For example, a level 2 guild would control about half of the economic power in a level 4 province. Also like provinces, holdings generally earn money for their regent.
Resources include the regent’s treasury, and regency points. The treasury is measured in Gold Bars, which is an abstract unit of account worth approximately 6000 gp. It is a combination of actual money, goods, influence, labour owed, special services and duties, etc. Regency points are an abstraction of the strength of the regent’s connection to the land, political power, and his or her ability to govern the population. They are closely tied to the regent’s bloodline.
Assets comprise everything else in a domain, including military forces, fortifications, trade routes, trade routes, etc. Certain assets, such as fortifications, have levels that describe their degree of development. A few assets earn money, such as trade routes, but most just cost money to maintain.
Domain level play happens in domain turns, which are one season long; four domain turns make up one year. Domain turns are further divided into three domain action rounds, each of which lasts one month.
Domain Turn Phases:
- Adjust domain attitudes
- Collect revenues and regency points
- Pay expenses
- Play out domain action rounds 1–3
1. Adjust domain attitudes
Each season, the opinions of the population towards the regent may rise or fall depending on past events and actions. Roll a d20 attitude check with relevant modifiers.
2. Collect revenues and regency points
Provinces (assuming average tax rate) and trade routes earn their level in GB, and guilds and temples earn 2/3 their level. Law holdings earn 1/3 their level, but can seize money from the income of the province and other holdings in it. Sources earn income as a guild of their level minus 4.
All provinces and holdings earn RP equal to their level, modified by the regent’s relevant skills for the specific type of holding.
3. Pay expenses
Most domain assets, especially military forces, fortifications, and the court have seasonal maintenance costs, which are paid from the realm’s treasury. (Maintenance costs of provinces, holdings, and trade routes are already factored into their income.)
4. Play out domain action rounds 1–3
Finally, choose actions for and play out the three month–long domain rounds. See Domain actions for specifics.
