City

Cities are made up of Foundations and Districts, both of which retain the yields of the underlying land. Foundations can only be constructed next to Districts. They are created instantly but cost 45 Influence and the cost is increased by 10 for every territory the empire controls. The first city an empire creates will always be its capital.

Every empire has a city cap, which starts at 3. Having more cities than the city cap will give increasing empire-wide Approval penalties.

Approval

Each city has an Approval value, which ranges from 0% to 100% affects the city's FIDSI production. Every city has a base value for 40% Approval. The capital has a base value of 50% Approval instead. If Approval drops too low, population will be consumed and become rebel armies. The strength of rebel armies scales with the strength of the city.

The average Approval in every city becomes the Empire Approval, which affects the empire's Dust, Science and influence production.

Both city and empire Approval have four distinct states: Mutinous (0-24), Content (25-60), Happy and Jubilant.

Population

Each city has four vocations. Population can be assigned to these vocations to affect their yield and slots in these vocations are obtained from certain Districts.

• Citizens produce +4 Food, +2 Dust and -3 Approval each.
• Artisans produce 4 Industry, 2 Dust and -3 Approval each.
• Scribes produce 1 Science and 2 Influence each.
• Destitute appears when population is higher than the available slots in the other vocations and will start building Shanty districts.

The Population tab can be automated to assign all new population to one vocation or balance it between the three vocations.

Populations possess inherent effects based on their faction. If a city has population from multiple factions it can choose the faction of the next population to grow.

Districts

Most Districts can only be constructed over a Foundation. They provide their own resource output in addition to their tile's native production. Districts will level up when surrounded by 4 other Districts. Clicking on a Foundation will display all Districts that can be constructed.

Improvements

Improvements confer extra benefits to the city. Most improvements can only be built once per city and the most powerful ones can only be built once per empire. The main way of unlocking improvements is via technologies but a few can also be obtained from quests, deed rewards, or population thresholds.
