Population

Population is divided into 4 categories of people: peasants, warriors, criminals and slaves.

All characters age at a rate of one year per day.

Peasants migrate to the city, the the number of migrating peasants depending on the average Mood.

If there are not enough living spaces people will become Homeless, which reduces their Mood by 14. Homeless people will sleep inside a Temple if one is built and in front of the Hall if no Temple is built.

Characters who are unhappy or listen to a Sermon of Faith at a Temple may become fanatic. Fanatic characters have the "Fanatically religious" thought thought (+12 Mood) and also enjoy pain. If fanatics stay unhappy for too long they can raise a rebellion.

If a character consumes alcohol too often they may become dependent on it. The character will want to drink alcohol every day and will gain increasingly negative thoughts each day they don't drink. The dependency may randomly end after a mental breakdown or if the character does not drink alcohol for a few days.

Once the city reaches at least 40 population the bishop may visit it for a few days. Lords have a number of special actions with the bishop. If a Temple is constructed the bishop will conduct the sermon. The bishop can provoke a religious uprising if he quarrels with any of the lords. If he dies from anything except natural causes an inquisition army will head to attack the city.

Needs, thoughts and mood

Every character has a Mood, which ranges from 0 to 100 and is the sum of all thoughts. Thoughts arise from events, desires and needs. If a need is fulfilled it will give a positive thought, while if it is unfulfilled it will give a negative thought. If Mood falls below 25 the character will become unhappy. The average mood of peasants affects the level of migration.

Needs generally decreases over time and they are fulfilled through specific actions character mostly perform on their own. The need for Rest is automatically replenished when not working. There are 5 needs:

Sleep: If it becomes completely empty, the character will collapse and fall asleep regardless of what is happening. It is satisfied by sleeping.
Food: If it becomes low it can lead to hunger and eventually starvation. It is satisfied by consuming food such as Flour, Meat or Rutabagas.
Rest: It is replenished slowly by not working and quickly by consuming alcohol at a Tavern.
Piety: It is satisfied slowly through praying and quicker at Temples or Altars.
Care: Only available to children. Is it satisfied by actions between parents and their child.
Sex: Only available to adults. Is it satisfied during dating.

Characters will pray between 8 AM and 9 AM. If there is a Temple they will pray there. If there isn't any but there is an Altar they will pray there. Otherwise they will pray at home but this will be less effective.

Slaves

Slaves are paid directly in resources rather than Gold and are given jobs before peasants. By default they are only paid in food but they can be given alcohol as well from the Finance menu. They are housed in Slave Barn buildings. The building requires a worker to give slaves their food and alcohol.

Slaves may or may not yearn for freedom, which is shown when hovering over them. If a slave yearning for freedom is unhappy they may attempt to escape. The chances of escape are higher if they are homeless.

Enough unhappy slaves can instigate a slave uprising.

Slaves can be obtained by punishing criminals or capturing them after a battle. They can also be bought and sold at the Holy Caravan. Each slave has a price of 15 Gold, which can be increased by the following:

+15 if the slave is 14-15 years old
+10 if the slave is 16-25 years old
+5 if the slave is 26-35 years old
+20 if the slave is female
+10 if the slave is not yearning for freedom

Criminals

Peasants who are unemployed and unhappy for too long will either leave the city or become criminals. Criminals will steal Flour, rob peasants on the street, and even break into the homes of peasants. After a few days they may become cutthroats.

Crime can be combated by deploying patrols, constructing Scaffold buildings or terror.
