Location

A location

A location is the smallest unit of land. There are four types of locations:

• Habitable locations have population and can support ownership or be entered by armies. Each habitable location has a dominant culture and a dominant religion, which are the culture and religion followed by most pops. Each habitable location also has a raw good and may construct or upgrade an R.G.O. to extract it.
• Impassable locations do not have population and cannot support ownership or be entered by units. If all adjacent locations are owned by the same country, the impassable location will also take on the country's color on the map.
• Corridor locations do not have population and cannot support ownership but can be entered by armies and are always connected to two habitable locations. If both connected locations are owned by the same country, the corridor location will also take on the country's color on the map.
• Seazone locations do not have population and cannot support ownership but can be entered by navies. Seazones have Maritime Presence from adjacent countries.
  • Sea Current locations function like seazones but also include a directional current, indicated by waves when the map is zoomed in and with arrows when the map is zoomed out. Navies traveling in the same direction as the current will move faster.

Map hierarchy

The map is divided into 6 levels of subdivisions:

•  Continent
•  Sub-continent
•  Region
•  Area
•  Province
•  Location

Various actions will target different levels of the hierarchy.

Provinces share and distribute  Food between its locations, and levies are raised from an entire province at once. Several cabinet actions target a province. Each province has a province capital, which has a star in the middle of the rank icon. If the province capital is occupied during war, all remaining locations are automatically occupied by the invader over a short period of time. If a province spreads over two market areas, the market where the province capital is located will be used to buy and sell food. Each province has its own provincial food storage. Any food that is not consumed by the pops in a location is contributed to the provincial food storage. If monthly food is negative, stored food will be consumed. If there is a deficit, the province will buy food from its market, and if there is a surplus, the province will sell food on its market. Armies in the province can also consume stored food if they would otherwise suffer attrition.

Provinces refer to both a static set of locations – sometimes called a province definition – as well as the set of locations that a country owns within that set. Thus, two or more countries can each have a province within the same province definition.

Integration status

Integration status represents how well a location is incorporated into the administrative apparatus of its owner. Every owned location falls into one of four different statuses. Conquered locations can be integrated via the Integrate Province cabinet action, and the integration speed depends on the number and culture of the population. Reaching Core status requires a 50% or more population of primary and accepted cultures.

Status	Pop growth	Effects
Colonized	All cultures	+0.1% Monthly Control
Conquered	All cultures	−0.5% Garrison Growth −10% Max Control −20 Pop Assimilation Speed −20 Local Pop Conversion Speed +50% Separatism
Integrated	All cultures	+5% Max Control −10 Pop Assimilation Speed +10% Separatism
Core	Primary and accepted cultures	Only Primary & Accepted Pops can Grow +20% Max Control +0.1% Monthly Control Owner gets Vision when Occupied

Rank

Each location has a  rank, which can be increased or decreased at any time. It affects what buildings can be constructed in the location, and increasing or decreasing the location rank will remove all incompatible buildings. The cost to increase a location's rank is impacted by market prices. Downgrading a location is instant and always costs 500  Gold and doesn't require goods.

Rank	Food capacity	Food production	Population	Other effects	Nahua Ritualism Doom	Base cost	Upgrade time	Requirements
Rural Settlement A Rural Settlement is land that is ripe for exploitation, representing everything from wilderness to clusters of countryside villages.	50	+10%		+100% Maximum RGO size +0.1% Population growth	+0.001 per month	500

Topography

Each location has a  topography, which represents the relief and elevation of its area.

Land topography

The topography map

Land locations have one of the following topographies:

Topography	Blocks vision	Movement cost	Expanding RGO time	Road building time	Development	Proximity impact	Other effects
Flatland Flatland represents terrain that does not have any major topographic variation, so there are no impediments for Army movement or Building development.
Hills A terrain with hills has variations in the topography, but the slopes are not as steep nor as high as those of mountains, so the penalties are also not as bad.	Sea Land	+50%	+25%	+100%	−25%	+25%	−10% Food production +1 Attacker penalty in combat −3 Possible frontage
Mountains Mountain terrain has high altitude and also steep slopes with relatively few and narrow flat areas, so it is more difficult for Armies to cross and fight in it, and also more difficult to develop.	Sea Land	+100%	+100%	+300%	−50%	+50%	−50% Population capacity −20% Food production +2 Attacker penalty in combat −4 Possible frontage Armies cannot enter during normal and severe winter
Plateau They represent relatively flat areas situated at high altitude, so they have some penalties compared to flatlands due to their elevation.	Sea	+25%	+25%	+50%	−25%	+12.5%	+1 Attacker penalty in combat −1 Possible frontage
Wetlands Wetlands are terrain that is partially flooded, generally due to being near a river, lake, or coast.		+50%	+25%	+100%	−30%	+25%	−10% Food production +1 Attacker penalty in combat −3 Possible frontage

Seazone topography

A seazone that has frozen

Seazones have one of the following topographies. Some seazones will freeze if the location experiences winter, which blocks ships from moving and allows armies to move on them. If an army is on a seazone when it thaws, half of it will be destroyed.

Topography	Can freeze	Effects
Atoll Atolls are circular low-altitude islands that usually encircle a lagoon.
Narrows Narrows are areas of sea with proximity of coast on many sides, like straits or the sea inside archipelagos, where there is not much space for movement.		+20% Movement cost of units −2 Possible frontage +1 Attacker penalty in combat Blocks vision from sea
Inland Sea Inland seas represent the land-enclosed seas like the Mediterranean or the Baltic.
Coastal Ocean This is the open seas between the continents, where only the best of ships can travel, but in the areas closer to the coast.
Ocean This is the open seas between the continents, where only the best of ships can travel.		+1 Naval attrition
Deep Ocean This is the open seas between the continents, where only the best of ships can travel, in the furthest areas from any coast.		+2 Naval attrition
Lakes Lakes represent inland bodies of water without any contact with the open sea except through possible rivers, so no ships of relevance are able to sail in them.		Blocks vision from sea
Salt Pan Salt Pans are barren expanses of extremely flat land formed by the evaporation of a lake or a pond.
Ocean Wasteland This is ocean sea outside of the main currents, so it is not a convenient path for ships to take, as they could end up stranded in the middle of it.		Impassable

Bug note: In 1.0.10 the +1 attacker penalty from narrows seemingly has no effect on dice rolls

Coast

Locations that are not adjacent to a seazone that cannot support ships, have a port or build ships and cannot be blockaded. Locations that are adjacent to a seazone can have a port and build ships and can be blockaded. In addition, locations that are adjacent to a seazone receive the following bonuses:

• +10% Local Monthly Development Growth
• +5% Local Food Production %
• +25% Local Population Capacity %
• +5% Supply Limit
• Have a Natural Harbor Suitability, which ranges from 0% to 100% and gives the following bonuses for each 1%:
  • +1% Harbor capacity
  • −0.3% Port buildings cost

Every coastal location has a Harbor Capacity, which is its Natural Harbor Suitability, increased by buildings that adds additional Harbor Capacity:

• Wharf +0.10
• Protected Harbor +0.10
• Dock buildings: Dock +0.10, Dry Dock +0.15, Shipyard +0.20, Grand Shipyard +0.25, Naval Base +0.30

Harbor Capacity can be more than 100%, providing more than 100% bonus. At 100% Harbor Capacity, it gives the following bonuses:

• +0.30 Local maritime presence
• −75% Proximity cost through port
• −5.0 Naval attrition
• −20% Disembark time
• −50% Trade embark/disembark cost

Straits

A Strait connects two Locations that are separated by a Seazone, but are close enough to each other so Armies can cross it without the need of a Navy. This is represented by a dotted golden line between the two locations on the world map.

Armies can travel across a strait so long as the strait is not blocked by a hostile fleet in the sea zone, unless both sides of the strait are owned by the army's controller or those they have military access with. Food and supply lines can go over straits regardless of any naval blockade.

Units who cannot retreat over a blocked strait to friendly territory or friendly naval transports after being broken in battle will be stack wiped. A manual forced retreat will have the army stay in place and restart the battle.

River

Certain land locations may have rivers between them, which give the following bonuses:

• +5% Local Monthly Development Growth
• +5% Local Food Production %
• +10% Local Population Capacity %
• +5% Supply Limit
• +5% Natural Harbor Suitability if location is coastal

If an army attacks immediately after crossing a river, it will receive penalties in combat. Rivers are not navigable by navies.

Tracing control from a proximity source downstream a river reduces the base  proximity cost between locations by −30, while tracing upstream only reduces it by −10. These bonuses are mutually exclusive with the ones provided by roads – only the highest reduction will apply.

Sound tolls

A few locations have a Sound Toll, which add an additional Gold cost to trade routes from other countries that pass through the location and give 25% of that  Gold to the location's owner. Hovering over a Sound Toll will list all trade routes going through the location and the income from each. The following locations have Sound Toll:

• Hormuz
• Kōnstantinoúpolis
• Roskilde

Countries can become exempt from Sound Tolls either through a Treaty or through events. Countries owning a Sound Toll location can remove exemptions but this will give the previously-exempt country the Sound Tolls Exemptions Broken casus belli.

Grand Canal of China

The Grand Canal of China is not visible on the world map and can only be seen as part of location modifiers. The canal flows through the following locations: Hangzhou, Wutong, Jiaxing, Songling, Suzhou, Wuxi, Changzhou, Danyang, Zhenjiang, Jiangdu, Gaoyou, Yancheng Baoying, Huaian, Huaiyin, Taoyuan Huaian, Suqian, Suicheng, Xuzhou, Peicheng, Guting, Jining, Wenshang, Dongping Yanzhou, Tongcheng, Liaocheng, Linqing, Guantao, Gexianzhuang, Gucheng Jingzhou, Dezhou, Sangyuan, Dongguang, Nanpi, Cangzhou, Qingzhou Hejian, Jinghai, Tianjin, Wuqing, Tongzhou, Beijing.

The Grand Canal of China gives every location it passes through the following bonuses:

• −10% Local Proximity Cost
• +100 Local Food Capacity
• +5% Local Monthly Development Growth

After 1345 there is a 10% chance each month that the canal will be damaged, replacing its bonus with a +10% Proximity Cost penalty. Afterwards, as long as the Emperor of China owns at least one location that is part of the Grand Canal of China, every 4 years it has a 2.5% chance to be offered to pay a very large amount of scaled gold to repair the canal and restore its initial effects.

Climate

The climate map

Each location has a  climate, which determines whether it can have winter effects and how severe they can be, as well as how much population it can support.

Climate	Max winter	Population capacity	Supply limit	Character life expectancy	Monthly development growth	Wheat output
Arctic Arctic represents areas with very cold winters.	Severe	−33%	−20%	−5	−25%
Hot Arid Hot Arid represents an area that has a severe lack of available water.	None		−10%	−5		−10%
Continental Continantal represents areas with cold winters.	Normal	+50%
Mediterranean Mediterranean represents areas with a perfect climate, where everyone wants to live.	None	+150%
Oceanic Oceanic represents areas with mild winters but high humidity.	Mild	+100%
Cold Arid Cold Arid represents an area that has a severe lack of available water but experiences winters.	Mild		−5%			−5%
Subtropical Subtropical represents areas with high average temperatures and mild winters.	None	+100%
Tropical Tropical represents areas with high average temperatures and no winter.	None	+50%		−5	−10%

Winter

Depending on climate, locations may have  winters, which give increasing penalties. The severity of a winter in each location at a given in game date is semi-random but limited by climate. Winters begin around January for locations in the northern hemisphere and around June for locations in the southern hemisphere. Armies cannot move into locations with Mountains topography with Normal or Severe winter level. Winters always start as mild and increase in severity then reverse and decrease in severity

Winter level	Effects
Mild	−25% Local Food Production % +2 Maximum Attrition
Normal	+1% Army Attrition −50% Construction Speed −50% Local Food Production % +5 Naval Attrition +2 Maximum Attrition
Severe	Constructions Stalled +2% Army Attrition −200% Local Food Production % +10 Naval Attrition +4 Maximum Attrition +25% Movement Cost

Vegetation

The vegetation map

Each location has a  vegetation type, which represents the foliage cover of its area.

Vegetation	Pop cap	Road building time	Development growth	Proximity impact	Movement cost	Blocks vision	Other effects
Desert Deserts are barren landscapes with little precipitation and almost no potential for plant or animal life.	+10K	+100%	−33%	+5%	+10%		Cyclones cause Sandstorms −33% Food production −5 Supply limit +50% Expanding RGO time
Sparse Sparse represent large flat areas of land with few or no trees.	+25K	−10%
Grasslands Grasslands represent terrain dominated by grass with little or no trees or shrubs.	+50K	−10%					+2 Supply limit
Farmlands Farmland represents anthropogenic terrain, devoted to crops and/or extensive pastures.	+100K	+10%	+10%	+5%	+10%		+10% Maximum RGO size +33% Food production +5 Supply limit
Woods Woods represent terrain with less dense vegetation than forests.	+50K	+25%	−20%	+12.5%	+25%	Sea	+10% Food production +2 Supply limit +1 Attacker penalty in combat −2 Possible frontage
Forest Forest represents terrain with dense vegetation.	+25K	+50%	−25%	+25%	+50%	Sea and land	+33% Expanding RGO time +1 Attacker penalty in combat −3 Possible frontage
Jungle A jungle represents terrain with dense forest and tangled vegetation that makes doing anything on the land difficult.	+50K	+200%	−25%	+50%	+100%	Sea and land	+50% Expanding RGO time +1 Attacker penalty in combat −4 Possible frontage

Roads

The road builder

Locations can be connected to each other via roads, which are drawn by selecting the start and end location in the Road Builder. The Road Builder can be set to prioritize proximity, army travel time, cost or construction time when drawing roads. Locations with roads receive the following bonuses:

• +5% Construction Speed
• +10% Institution Growth
• +25% Local Monthly Development Growth

Roads come in four levels, which are unlocked by the advances with the same name and provide additional bonuses. The Road Builder includes a button to automatically upgrade all existing roads to a higher level.

Road	Movement cost	Market access cost	Proximity impact	Maintenance
Gravel Road The Road has a loose gravel surface. Better than mud.	−25%	−10%	−20	0.01 Sand
Paved Road The Road has a solid paved surface which is much better for travel.	−30%	−15%	−25	0.01 Sand  0.01 Masonry
Modern Road The Road has a modern flat surface and is of good quality.	−35%	−20%	−30	0.01 Sand  0.01 Masonry
Railroad The Road has been upgraded to a rail connection, massively increasing travel speed and logistics.	−80%	−25%	−35	0.01 Sand  0.01 Masonry  0.01 Steel

Control

Main article: Control

Each location you own has a  Control percentage, expressing how much the central government can tap into the ressources of the location. It has a wide range of effects, from directly impacting how much the local population can be taxed, to the amount of levies they will contribute when called. A lack of control in a location reduces the crown power gained from its population, while also decreases the manpower and sailors available locally and weakens the market attraction of your own markets, making them likelier to belong to foreign markets if they have low control.

Each percent of control has the following effects on locations:

• +1% Local Crown Power
• +1% Levy Size
• +1% Monthly Manpower
• +1% Pop Assimilation Speed
• +1% Local Pop Conversion Speed %
• +1% Local Pop Promotion Speed %
• +1% Monthly Sailors
• +0.5% Local Market Protection

Each percent of control above 50% has the following effect on locations:

• −0.5% Mercenary Size

Each percent of control below 50% has the inverse effect:

• +0.5% Mercenary Size

On top of these modifiers, the effective  Tax Base of a location is calculated by multiplying the  Potential Tax Base with the location's control.

Development

Development at the start of the game

Each location has a  development score, which represents how cultivated the land is and how much it is used by the pops living there and can be increased via the Develop Province cabinet action. Each point of development gives the following:

• +0.01 Blockade Force Required
• +1 Supported Building Levels
• −0.1% Buildings Cost
• +1% Construction Speed
• −0.2% Local Proximity Cost
• +0.2% Institution Growth
• +0.1 Character Life Expectancy
• +100 Maximum RGO Size
• +0.0025 Migration Attraction
• +1% Local Food Production %
• +2.5% Local Population Capacity %
• +2% Supply Limit
• +0.1% Market Attraction
• +5 Maximum Stockpile Capacity
• +1% Occupation Time

Prosperity

Each location has a  prosperity percentage, which represents how prosperous and resourceful a location is. Prosperity rises naturally over time, but will decrease as a result of low pop satisfaction, diseases, sieges, occupation, or looting from enemy armies. Negative prosperity is also called devastation.

Every 1% prosperity above 0 brings the following bonuses:

• +0.1 Character Life Expectancy
• +0.001 Migration Attraction
• +0.00004 Local Monthly Development
• +0.002% Population Growth

Every 1% prosperity below 0 brings the following penalties:

• +0.5% Construction Speed
• −0.1 Character Life Expectancy
• +0.5% Mercenary Size
• −0.01 Migration Attraction
• −0.00004 Local Monthly Development
• −0.5% Local Food Production %
• −0.0005% Local Monthly Literacy
• −0.5% Local Pop Promotion Speed %
• −0.005% Population Growth
• −0.5% Production Efficiency
• −0.5% Raw Materials Output

Weather Fronts

Weather fronts give the following effects in 3 months in each location they pass through, depending on whether the location currently has a severe winter or not.

Normal, Mild or No winter	Severe Winter
+25% Local Food Production % +2 Naval Attrition	+5% Army Attrition −1 Local Maritime Presence −25% Local Food Production % +10 Naval Attrition −50% Raw Materials Output +50% Movement Cost

Most weather fronts are the size of an area. There are three weather fronts that are the size of a subcontinent and will take place each year:

• The Monsoon starts at the beginning of June at the bottom of India and will expand through the subcontinent of India before moving north-east into parts of South East Asia and China.
• The Post-Monsoon starts in at the beginning of October in the region of Xinjiang and will move south, south-west and south-east.
• The Polar Vortex has a 75% chance to appear each year at the beginning of February from the north of the map.

Cyclones

A cyclone

Locations touched by a cyclone will gain a negative modifier for 3 months that scales with the strength of the cyclone and the location's distance from the eye of the storm:

• Locations that do not have Desert vegetation will gain the Wind Damage modifier
• Locations that have Desert vegetation will gain the Sandstorm modifier
• Coastal locations may gain the Storm Surge modifier

Max Wind Damage penalties	Max Sandstorm penalties	Max Storm Surge penalties
−0.5 Local Maritime Presence −5% Local Food Production % −1% Local Monthly Prosperity +10 Naval Attrition −15% Raw Materials Output +25% Movement Cost	+5% Army Attrition −1 Local Maritime Presence −15% Local Food Production % −1.5% Local Monthly Prosperity +10 Naval Attrition −25% Raw Materials Output +25% Movement Cost	−0.5 Local Maritime Presence −1% Local Monthly Prosperity +10 Naval Attrition −15% Raw Materials Output

Cyclones will always move from their origin to their dissipation location, but their path towards the dissipation location will be random.

Origin	Possible dissipation locations	Strength	Monthly chance
North Polynesian Sea	Alaska Sea	Full	8.3%
Erg Aoukar	North Eastern Atlantic Cape Verde High Sea Central Atlantic High Seas	Half	8.3%
Caspian Sea	Saryeshik-Atyrau Sands	Half	8.3%
Indian South Current	African High Sea	Half	8.3%
Andaman Sea	Lushai Sreepur	Full	4.2%
Indonesia High Sea	Indian Tropic of Capricorn Gibson Desert	Full	4.2%
Pacific Polynesia Current	South Pacific Ocean Tasman Sea	Full	4.2%
Eastern Pacific High Sea	Pacific North Equatorial Current Eastern Pacific High Sea Colorado Delta	Full	4.2%
Al Jaza'ir	Arabian Sea Red Sea Marshaq Cape	Half	4%
South Indian Countercurrent	Mozambique Channel Eastern Southern Ocean	Full	2.8%
Arabian Sea	Dubbi Jāleq	Full	2.1%
Cape Verde High Sea	random	Full	80% in May, June and July

Tornadoes

Tornadoes move from one end of a province to another, giving all locations they pass through in a straight line the following penalties for 3 months:

• +10% Army Attrition
• −2 Local Maritime Presence
• −20% Local Food Production %
• −2.5% Local Monthly Prosperity
• +10 Naval Attrition
• −100% Raw Materials Output

Tornadoes have a 50% chance to appear in the regions of East Coast, Aridoamerica or Louisiana each month.

Tornadoes have 1% chance to appear in Europe each year.

Dangers

Danger locations

Dangers are present in certain locations and displayed in the Dangers map mode. When a danger strikes the affected countries will be given the option to pay scaled  Gold to give the location a Recovery Efforts modifier, which lasts for 10 years and gives the following effects:

Minor Recovery Efforts	Major Recovery Efforts
−10% Buildings Cost +0.5% Prosperity Recovery	−20% Buildings Cost +0.5% Prosperity Recovery

Volcanoes

 Volcanoes are present in certain locations and appear red on the Dangers map mode. Each Volcano has a very low chance to erupt each month.

Eruption	Monthly chance	Population	Prosperity	Development	RGO Level	Buildings	Volcanic Soil	Recovery Efforts	Recovery Cost
Minor	0.008%	−10%	−20%	−0.25	−1		20 Years	Minor	200% of income
Moderate	0.006%	−20%	−50%	−0.5	−2	−1	50 Years	Minor	400% of income
Major	0.004%	−30%	−70%	−1	−3	−1 per 8 buildings	70 Years	Major	600% of income
Catastrophic	0.002%	−50%	−95%	−2.5	−5	−1 per 6 buildings	100 Years	Major	1000% of income

After an eruption the location will gain the Volcanic Soil modifier, which is visible on the map and gives the following effects:

• +50% Local Food Production %
• −25% Expanding Raw Materials Time

Earthquakes

 Earthquakes can occur along certain lines that pass through locations and appear orange on the Dangers map mode. Every month there is a chance that an earthquake will take place somewhere in the world. The epicenter location will take the full penalties of the earthquake while all adjacent locations will take half of the penalties and will not lose buildings.

Earthquake	Monthly chance	Population	Prosperity	Buildings	Army health	Cities	Recovery Efforts	Recovery Cost
Minor	1.6%	−10%	−20%	−1 per 10 buildings	−33%	Unchanged	Minor	10 times the location's tax base
Major	0.4%	−20%	−50%	−1 per 8 buildings	−50%	Unchanged	Major	20 times the location's tax base
Catastrophic	0.1%	−33%	−75%	−1 per 6 buildings	Killed	Downgraded to Town	Major	30 times the location's tax base

Historical earthquakes

Historical  earthquakes occur in every game, but each one happens only once. They have predetermined locations and years, and also affect all neighboring locations. Most of the time when a historical  earthquake occurs, players will have the choice between different options, each with different penalties.

Tier	Population	Prosperity	Buildings	Army health	Recovery Cost
Minor	−5%	Severe penalty	−1 per 15 buildings	−33%	7 times the location's tax base −25
Major	−10%	Ultimate penalty	−1 per 10 buildings	−50%	15 times the location's tax base −50
Catastrophic	−20%	Radical penalty	−1 per 8 buildings	Killed	20 times the location's tax base −100

Neighbor locations
Population	Morale	Prosperity	Buildings
−5%	−33%	Weak penalty	−1 per 20 buildings
−5%	−33%	Severe penalty	−1 per 15 buildings
−10%	−50%	Extreme penalty	−1 per 10 buildings

Below is the list of all scripted  earthquakes. Most of them have a 10-year time window in which they will occur.
