Empire

Version

This article has been verified for the current PC version (3.4) of the game.

A galaxy populated by multiple empires

An Empire is a group of planets and star systems that are ruled by the same government and controlled by a single player (or AI). Empires may have a variety of governments such as a democracy, oligarchism, despotism or imperial rule.

Ethics are the most defining features of a space empire; they affect the behavior of AI empires, likely technologies, available policies and edicts, valid government types, the opinions of other empires, and - perhaps most importantly - provide the fuel for internal strife in large and diverse empires. Civics are the second-most defining features of a space empire; they affect the finer details of the empire's internal structure as well as having certain effects on the empire's behavior.

It should be noted that the name of the player empire and its government structure can always be changed in the government window.

Each empire starts with a basic setup that's modified by its origin, authority, civics, and species archetype.

Default home system

The default home systems deposits total 12-13  Energy, 12-13  Minerals, and 5-6  Research of up to two random types. The smaller deposits won't have mining or research stations built on them yet.

Unplayable origins

The following origins have no effects and are not available to player empires.

Origin	Source	Description
Elder Race	Fallen Empires	This civilization greatly predates the current generation of galactic powers. Eons of stagnation gradually reduced their empire to a mere shadow of what it once was.
Enlightened	Enlightened pre-FTL civilizations	The natural development of this civilization was greatly accelerated by the interference of another party, who helped them become a spacefaring culture.
Separatists	Rebel empires	This civilization came into being when it rebelled and seceded from another empire.
Hegemon Subordinate	Empires generated by the  Hegemon origin	This civilization established early contact with their immediate alien neighbors. Gradually, over the span of a century, they were subordinated to one of those neighbors, who masterminded the birth of an interstellar union with them as its leader.
Imperial Liege	Overlord empire generated by the Imperial Fiefdom origin	An ambitious overlord who has spent considerable time and efforts in subduing their closest neighbors to serve their every need. They are slowly growing more indolent as they devolve more and more responsibility to their vassals.
Khanate Successor	Horde successors	This civilization arose out of the ashes of the Great Khan's mighty empire.

Capital

Authority	Effects
Non-Gestalt	+5 Stability  +10 Amenities  +100% Governing Ethics Attraction
Hive Mind	+5 Stability Amenities +10 Deviancy −20
Machine Intelligence	+5 Stability Amenities +10 Deviancy −20 Drone Resource Output +5%

The capital is the ruling seat of an empire as well as the final destination for all its trade routes. An empire's capital can be moved once every 10 years for a cost of 250  influence if the empire is at peace. An empire's capital planet and system are marked by gold star corners on the system and galaxy maps. The capital has its own world designation with the special effects.

Empire size

Authority	Size Effect
Hive Mind	−25%
Dictatorial	−10%
Corporate	+25%

 Empire size represents the increasing difficulties of managing a large empire. Each point of  empire size above 100 increases tradition cost by +0.2% and technology cost by +0.1%. This penalty is affected by certain authorities, as noted in the table on the right. Empire size also affects several other mechanics, typically increasing the cost to perform certain actions. Specifically, each point of empire size has the following effects:

•  +10 unity cost to reform the empire's government
• +10 plus +6 per planetary ascension tier unity cost to increase planetary ascension tier
•  +1% edict cost
•  +0.25 infiltration daily for other empires building a spy network
•  +2 naval capacity use required to maintain power projection

 Empire size is increased by each of the following owned by the empire:

Source	Size
Colony	10
Branch offices	2
System	1
Pop	1
District	0.5

Each of these categories is affected by its own set of modifiers:

Source	Empire Size
Courier Network tradition	−25% from systems and colonies
Private Prospectors civic	−33% from systems
Divided Attention civic	−50% from colonies
Imperial Prerogative ascension perk	−50% from colonies
Machine Intelligence authority	+50% from colonies
Intergalactic Directives Regulated Growth	+5% from systems
Intergalactic Directives Ensured Sovereignty	+15% from systems +5% from colonies
Intergalactic Directives A Voice for All	+25% from systems +15% from colonies
Modular Depots tradition	−25% from districts
Construction Templates technology	−10% from districts
Franchising civic	−25% from branch offices
Imperial Charter modifier	−25% from branch offices
Per Planetary Ascension tier	−5% from the colony, districts and per pop on the colony

Source	Empire Size
Docile species trait	−10% per pop
Streamlined Protocols species trait	−10% per pop
Unruly species trait	+10% per pop
High Bandwidth species trait	+10% per pop
Stellar Culture Shock planet modifier	−50% per pop
Per governor skill level	−2% per pop
Fanatic Pacifist ethic	−30% from pops
Subsumed Will civic	−20% from pops
OTA Updates civic	−20% from pops
Pacifist ethic	−15% from pops
Machine Intelligence authority	−15% from pops
Beacon of Liberty civic	−15% from pops
Psionic Theory technology	−10% from pops
Domination tradition tree finish	−10% from pops
Harmony tradition tree finish	−10% from pops
Synchronicity tradition tree finish	−10% from pops
The Greater Good resolution 4 or 5	−10% from pops
Galactic Mobilization	+2% from pops

Note that the "from pops" modifiers listed above apply on an empire-wide basis, whereas the "per pop" modifiers (also presented in game as "from pops") apply only to specific pops (e.g. those with the given trait). These are two different categories of size modifier: both groups are additive within themselves, but multiplicative between each other. As an example, pops with the  Docile trait in a sector governed by a level 1 governor in a  Fanatic Pacifist empire with  Beacon of Liberty will each contribute the following to the empire size:

$${\begin{aligned}{\text{Total}}&={\text{Base}}&\times (1-&{\text{Per pop modifiers}})&\times (1-&{\text{From pop modifiers}})\\&=1&\times (1-&[0.10+0.02])&\times (1-&[0.30+0.15])\\0.484&=1&\times 0.88&&\times 0.55&\end{aligned}}$$

Sector systems

Sectors are administrative regions within an empire. Every empire will start with a core sector, named after the homeworld and extending up to four hyperlanes away from the capital. Any colonized planet more than four hyperlanes away from another sector capital can be selected to become the sector capital of a new sector, with the planet becoming marked by blue star corners on the system and galaxy maps. The new sector will extend up to four hyperlanes away from the sector capital. Wormholes and Gateways are not counted for this calculation. Each sector can have a Governor assigned to it.

All sectors, including the core sector, can be given a Sector Focus. Choosing a Sector Focus will make the sector develop itself automatically towards a given direction as long as it has resources, reducing micromanagement.

Energy credits and minerals can be added to a Shared Stockpile for all Sectors to use or given manually to each Sector. Resources transferred to sectors will be converted into a wildcard resource at a 1:1 ratio and it can be spent on planetary construction as though it were energy credits or minerals. Shared and Sector stockpiles are limited to the amount of energy credits you may store. Beyond that, it is wasted.

Relative power

Relative Power is a measure of how much empires are ahead of one another in terms of resource production, fleet power or researched technologies. A Relative Power of Superior/Inferior means that an empire has 50% more (1.5x) resource production, fleet power or researched technologies and a Relative Power of Overwhelming/Pathetic means that an empire has 150% more (2.5x) resource production, fleet power or researched technologies.

Relative Power is split into three categories: Fleet Power, Economic Power and Technology Level.

Fleet Power: The combined fleet power of every owned fleet.

• +1 per 1 Fleet Power

Economic Power: A weighted sum of all monthly income, including income from trade agreements. Monthly spending is not part of this score. The various resources are weighted the same as their base market price (base energy price for 1 unit):

• +1 per basic resources
• +2 per  Consumer Goods
• +4 per  Alloys
• +10 per common strategic resources
• +20 per rare strategic resources

Technology Level: 60 + the combined base Tech Cost of all researched technologies, divided by 100. Repeatables only count 0.33x as much as regular technologies.

• +60 Base Technology Level
• +0.01 per 1 base Tech Cost of all researched technologies, including repeatable technologies

The formula to calculate the overall power of an empire is: ${\text{Overall Power}}={\text{Fleet Power}}*2+{\text{Economic Power}}*3+{\text{Technology Level}}*1$

Victory score

Victory score tallies an empire's total accomplishment. The empire that has the highest score when the Victory Year arrives is declared winner. The Victory Year is configurable and can be disabled altogether. An empire will always declare victory, if it's the only one that can do so. All players may continue the game session normally even after an empire declares victory and the victory is, in practical terms, of little concern.

The Victory Window shows a total score for each empire and its ranking, as well as a breakdown by category. The categories are as follows:

Economic Strength: +1 per 1 Economic Power based on Relative Power OR +5000 if the Empire has no economy.

Technology Level: 60 +0.25 per 1 Technology Level over 60 based on Relative Power

Number of Systems: +10 per system

Number of Colonies: +50 per colony

Number of Pops: +2 per pop, regardless of type

Subject Empires: +50% of a subject empire's score is given to the overlord

Federation: +10% of each other federation member's score is shared by all federation members

Crisis Ships Killed: +10 per crisis ship destroyed

Relics Collected: Each Relic grants a large amount of score. The score of each Relic is shown on the Relics page.

Empire modifiers

Empire Modifiers are gained through a variety of actions such as event choices or diplomacy with enclaves. They affect the entire empire and as such bring large benefits or penalties.

Permanent modifiers

Permanent Empire Modifiers are always positive and last the entire game. They can only be gained through events.

Market Nexus	−10% Market Fee	Galactic Market Station Can be captured	Hosts the Galactic Market Station
Universal Translator	+10% Monthly Society Research +15% Envoy Improve Relations	Random Event during any First Contact with Other Empires Grant Extra Funding Choice (−1000  Energy)	Although the so-called "Universal Translator" falls short of the initial promises of our researchers to instantly facilitate communication with any and all intelligent species, it is nevertheless a highly useful communication tool that now forms part of the standard equipment of our envoys and social scientists.
Flagellating Movement	+5% Evasion	Space Amoebas First contact choice.	We have updated our Evasive fleet stance protocols based on observations of the Space Amoebas' flagella.
Amoeba Hunter	+33% Damage to Space Amoebas 1000 Energy per destroyed Space Amoebas fleet	Militarist, Xenophobe or Genocidal Space Amoebas First contact choice.	Amoeba carcasses are rounded up after battle and their internal organs harvested for valuable organic compounds, bringing in 1000 for every fleet destroyed.
Amoeboid Pacification	Space Amoebas will not attack owned ships	Pacifist or Xenophile Space Amoebas First contact choice.	Fleets regulate radiation venting when approaching Space Amoebas, and the spaceborne creatures no longer recognize us as a threat.
Crystal Focus	+5% Energy Credits from Jobs	Crystalline Entities First contact choice.	Improved transmission mediums modeled after the Crystalline Entities' unique internal structures minimize resistive losses in energy production and distribution.
Crystal Hunter	+33% Damage to Crystalline Entities 500 Minerals per destroyed Crystalline Entities fleet	Militarist, Xenophobe or Genocidal Crystalline Entities First contact choice.
