Building somewhere to live

Your people need somewhere to live. The good news is that it's not very hard to make such a place. Your cities will automatically expand to accommodate extra people (unless you specify otherwise). However, cities are not very easy to defend, they don't have the nice walls that castles do. Hence you need to build walled cities.

Adding some walls

There are three types of city. Normal, walled and fortified. This applies also to towns and villages, a city is basically a very big town. Normal cities have no walls and are very hard to defend. Walled cities are much easier to defend, you have a wall which stops the enemy from just walking in, they need to get past the wall and your archers are on it. Finally there are fortified cities. These have crenelations, murder holes, towers, stronger walls and stronger gates.

Cities are free to build, your population will build them themselves without any orders for you. Adding walls and fortifications costs materials and requires a supply of stone. The cost is based on the number of people that will be able to live behind the walls. A walled city will be able to hold twice that number of people during a siege but it will not be comfortable or pleasant.

Population Capacity	Walled City	Fortified City	Upgrade cost
25,000	1.5 Materials	2.5 Materials	2 Materials
50,000	3 Materials	5 Materials	3 Materials
75,000	4.5 Materials	7.5 Materials	4 Materials
100,000	6 Materials	10 Materials	5 Materials
125,000	7.5 Materials	12.5 Materials	6 Materials
150,000	9 Materials	15 Materials	7 Materials
175,000	10.5 Materials	17.5 Materials	8 Materials
200,000	12 Materials	20 Materials	9 Materials
225,000	13.5 Materials	22.5 Materials	10 Materials

Walls take 2 turns to create, you can also knock down old walls and reuse the materials for other things. Only half of the materials are able to be regained in this way. If you want to upgrade from walled to fortified then you must pay the upgrade cost. This will take one turn.

Expansion

Expanding walls from one tier to the next is not as expensive as it looks. When you expand the walls you can choose to knock down the old ones and re-use the supplies from that. This gives a huge discount as you can re-use 50% of the previous stone (and thus keep 50% of the original cost). The problem is that it will take two turns to make this upgrade. Any attacks during the first turn will find you have no walls and any during the second year will find that your walls are stronger the later in the year that they arrive.

The advantage of leaving the old walls intact is not only that while building the new ones you have still have the old ones to allow you to defend your people but also that should an enemy later breach your outer walls, you have inner walls to fall back to. A multi-walled city can hold out much longer then a single walled city.

Others

To build ships you need a shipyard, to worship a deity you need a temple and so on. These buildings are built for just 5 materials per turn. They take 2 turns to construct and only one building can be created at once in each city. You may not have more than one of each type of building per city. A city counts as anywhere with at least 25,000 people. You may not have more than one of each type of building in each city.

Only one building can be constructed or repaired at once per city. All buildings are assumed to be within the walls as long as the cities walls are far enough out, in the table below this is the "wall position" field. Note that building walls does not use up the construction capability of a city for that turn.

Building	Wall position	Purpose
Shipyard	50,000	100 shipbuilding points
University	50,000	50 mundane research points per turn
Magical academy	50,000	50 magical research points per turn
Temple	50,000	Allows resurrection
Castle	It is a wall	Holds 5,000 people
Custom project	Depends	Depends on what you're making

If you do not have a supply of stone to the city then buildings take twice as long to build and walls and castles cannot be built at all.

Nomads

Nomads have a very big problem, they don't build cities. This means that they are normally poor defenders. They cannot construct ships for themselves, research, train mages because they do not build. They can train men as their groups count as temporary cities and can thus perform training.
