Guardians are extremely powerful Spaceborne aliens added in various DLCs. They can be found in special predetermined systems and rival moons in size and mass. They are marked with a skull icon both in the fleet power box and on the galactic map, and the exact strength number can only be seen with debug mode on. Each guardian has a unique event chain. While one can just stumble over one during exploration, they can also be found with the help of the Curator Enclave. Guardians have an immense amount of health and should only be engaged mid-late game.
Guardians get various bonuses to make them stronger based on the game difficulty. AI empires will only attack a guardian if their fleet power is at least 40k.

Empire with the 
Reanimators civic that kill an organic guardian will gain the option to issue a special project that costs 10000 
Asteroid Hives
 |
只可用于 Leviathans DLC 已启用。 |
A random system in the galaxy will have an asteroid belt containing 5 unique crystalline asteroids with deposits of 6-8 
If the system is claimed with a Starbase the Asteroid Hives will awaken with the following MTTH based on the number of constructed mining stations:
| Mining Stations | 0 | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|---|
| MTTH | 100 years | 33.3 years | 11.1 years | 3.7 years | 1.2 years | 0.4 years |
The Asteroid Hives use only strike craft as their weapons. As a result carrier ships are the ideal counters as the Asteroid Hives have no point-defense themselves and launched strike craft will engage and destroy the enemy ones before attacking the guardians. In addition carrier ships have point defenses themselves.
Defeating all 6 Asteroid Hives will grant 500 
Automated Dreadnought

Dimensional Horror
|
|
只可用于 Leviathans DLC 已启用。 |
A random black hole system in the galaxy will appear empty on sensors but reveal the Dimensional Horror when first entered, a nightmarish creature that entered only partially in the current dimension. The guardian cannot move but its tentacles can strike across the entire system. Its weapons ignore armor but do -75% damage to shields. The Dimensional Horror has equal amount of shields, armor and hull as well as no evasion, making the long-ranged Kinetic Artillery or size X weapons the ideal counter.
Defeating the Dimensional Horror will leave behind a dimensional rift with a special project that takes 140 days to be researched. Once examined, it will give the following rewards:
- 4000-6000
物理学研究 Research - 4000-6000
社会学研究 Research - Unlock the
Jump Drive technology with 50% progress if not already researched -

A random class A star system in the galaxy will house the Enigmatic Fortress, a massive space station guarded by numerous unique defense platforms. The Enigmatic Fortress uses regular components and can be countered appropriately. The installation consists of the following stations:
| 1 Ancient Vault | 2 Ancient Guardian | 2 Ancient Warden | 4 Ancient Defender | 8 Ancient Sentinel |
|---|---|---|---|---|
|

Ether Drake
|
|
只可用于 Leviathans DLC 已启用。 |
A random class F star system in the galaxy will feature a 
Molten World called Dragon's Hoard guarded by the Ether Drake, a dragon-like guardian the size of a moon. The Ether Drake uses only energy weapons that do -20% damage to shields and has high hull and armor but no shields itself. As a result, shielded fleets equipped with energy weapons are the ideal counter. Initially the Ether Drake will stay and guard Dragon's Hoard but should it be attacked enough to lose 20% HP it will go to two random systems belonging to the attacker and destroy their starbases. After the Ether Drake leaves if the systems were colonized the starbases will be rebuild into frontier outposts. If the Ether Drake loses 85% HP it will stay or retreat to Dragon's Hoard and heal.
Defeating the Ether Drake grants the following rewards:
- 300
影响力 - The Empire Capital gains the unique
Dragonslayer Monument planetary feature - The Empire gains the
Ether Drake Trophy Relic - If an Admiral was leading the fleet that defeated it, it will gain the
Dragonslayer trait - The Dragon's Hoard, which outputs 30
能量币 and 30 矿物 . Building a mining station above it will reveal both of the following within 50 years, though not necessarily at the same time:- Remains of the Ether Drake's mate: The remains can be studied to unlock the
人造龙鳞装甲 technology. Alternatively, they can be grinded for 100-4000 矿物 and 1000-100000 社会学研究 research. - Ether Drake's egg: The egg can be smashed for 300
影响力 or used in a timed special project that takes 50000 社会学研究 research to hatch a controllable Ether Hatchling with about 7K Fleet Power. Unlike the controllable Space Amoeba, the Ether Hatchling will never grow to a full sized Ether Drake.
- Remains of the Ether Drake's mate: The remains can be studied to unlock the

逝者军势 civic, it can be brought back.
Infinity Machine
|
|
只可用于 Leviathans DLC 已启用。 |
A black hole system in the galaxy named Gargantua will house the Infinity Machine, the only guardian in the game that's not hostile. At first no interaction with the Infinity Machine is possible but a year or two after being discovered the guardian will send a transmission and start a special project that requires 360 days and at least a level 3 scientist leader to be finished. Completing the special project allows the following options:
Materialist empires can attempt to hack the Infinity machine. Chance is 50% and if successful it permanently grants a +5% 研究 Output empire modifier as well as either the 正电子人工智能 Positronic AI正电子人工智能 or the
零点能源 technology. If both were already researched it will grant 1000-5000 社会学研究 research. For
格式塔意识 empires this is the only option. This approach destroys the Infinity Machine.
Spiritualist empires can declare the Infinity Machine a divine object, granting a +5% 
幸福度 empire modifier.
Militarist empires can destroy the Infinity Machine with an army without fighting it to gain the same bonuses as when defeating it.- All empires can communicate with the infinity Machine after the special project is completed. Militarist and
极端平等主义 empires can try saying the liar's paradox but the guardian merely finds paradoxes boring. The empire can offer to help it and start a special project that requires 1800 days and a science vessel to be finished. Finishing the project will have one of the following outcomes.- 50%: the project fails but the Infinity Machine will reward the empire with the 正电子人工智能 Positronic AI
正电子人工智能 technology. If already researched it will grant the
零点能源 technology. If both were researched it will grant the empire a +5% 研究 Output empire modifier. - 25%: the project succeeds and the Infinity Machine enters the black hole. It will grant the 正电子人工智能 Positronic AI
正电子人工智能 technology. If already researched it will grant the 零点能源 technology. If both were researched it will grant 150 影响力 . In addition the black hole will get a 4 研究 deposit. - 25%: the project succeeds and the Infinity Machine enters the black hole and shrinks it to a smaller size renamed Pantagruel which will get a 10
研究 deposit. The empire will get 200 影响力 and permanently gain the Mirror of Knowledge modifier ( +10%
研究速度 ). In addition a Curator Enclave can be contacted and given some info for 500 Engineering Research.
- 50%: the project fails but the Infinity Machine will reward the empire with the 正电子人工智能 Positronic AI
Alternatively the Infinity Machine can be attacked, forcing it to open and become aggressive. The guardian comes equipped with lasers, strike craft, heavy shields and regeneration components and has good evasion. As a result, shielded fleets using kinetic weapons are the ideal counter. Destroying the Infinity Machine will allow it to be broken down for 700-4000 
Horizon Signal
If the Horizon Signal event chain has been started entering the Gargantua system, whether it's the first time or not, will have the Infinity Machine initiate contact and ask you for 800
Spectral Wraith
|
|
只可用于 Leviathans DLC 已启用。 |
The Spectral Wraith is a guardian that can only appear during the mid-game years. A random pulsar in the galaxy when surveyed will reveal a unique 
Pulse Germination modifier. The first empire that surveys the pulsar will be shown an event window pointing to the date when the mid-game starts and hinting that is the system where the Spectral Wraith will spawn.
Unlike other guardians the Spectral Wraith is completely mobile and can travel anywhere in the galaxy. It will spawn in one of three colors: red, yellow or blue. In systems with a star of the same color the Spectral Wraith will gain -50% 
Defeating the leviathan gives a permanent empire modifier with the following effects:

Stellar Devourer
|
|
只可用于 Leviathans DLC 已启用。 |
A random class M star system in the galaxy will appear empty on sensors but reveal the Stellar Devourer when entered, a glowing spaceborne entity that feeds upon stars. If the Stellar Devourer was engaged and did not lose at least 67% HP it will attack one of the attacker's systems until the starbase is disabled and then stay for 90 days until retreating. If the system is colonized all planets will get -25% 
The Stellar Devourer's weapons are mostly energy and torpedoes, so shields and point defense are an effective counter. It has extremely high hull and point-defenses, but no armor or shields, making hull-damaging weapons such as plasma weapons and particle launchers the most effective counter.
Defeating the Stellar Devourer will give the option to issue a special project to investigate its remains that takes 60 days to be finished. Once examined it will give the following options:
- Harvest the body's energy deposits for a large bonus of 10,000
能量币 , 2000 矿物 and 80 影响力 . - Try to reignite the Sun in the leviathan's home System. The Project has a 30% chance to kill the scientist and its ship but is guaranteed to turn the whole System more habitable: All Frozen Planets will become Arctic planets. All other planets undergo a temperature increase as well, rerolling them completely.
Xenophobe and Militarist empires have the option to instead gain the unique 
Stellar Devourer Trophy planetary feature (+8 
The Elder One
|
|
只可用于 Leviathans DLC 已启用。 |
A random planet in the galaxy might contain an archaeological site named The Broken Gates. It has 4 chapters, each one granting 1-5 
Engineering Research or release it. Releasing it will destroy the system identically to a Star-Eater and the Elder One will emerge but not become hostile. If let out the Elder One will contact the empire 10 days later and offer to rebuild the starbase of the destroyed system and grant an empire modifier that gives +6% 
Growth Speed. Refusing will grant 150-300
The Elder One fights identically to the Dimensional Horror. If killed the empire modifier provided will be removed.
Corrupted Avatar
 |
只可用于 Distant Stars DLC 已启用。 |
A randomly placed system with a wormhole will bring an event window when first entered, mentioning a signal coming out of the wormhole and hinting that this specific wormhole is different from the rest. Exploring the wormhole will reveal its connection to a trinary system in the galaxy with no hyperlane connections. Said system is guarded by a Corrupted Avatar (aka Psionic Entity). The Avatar uses only energy weapons that ignore armor but do -75% damage to shields. It has moderate hull and strong shields but no armor or PD, making missiles and strike craft very effective.
| Base stats | Weapon components | Core components |
|---|---|---|
|
 4x  Psionic Blast

Defeating the Corrupted Avatar allows free access to the system, which contains a 
The Corrupted Avatar can be avoided by setting a science ship's stance to passive and guiding it around the guardian. This approach does not allow colonizing the Gaia World but it does allow the research reward to be claimed.
If a Sentry Array has been completed the system housing the Corrupted Avatar can be seen but cannot be entered with Jump Drives until the system has been entered via the wormhole first.
Unlike other guardians the Corrupted Avatar will always be present if the required DLC is installed. Its system is accessible only via a wormhole which will appear even if wormholes were disabled on game startup.

|
只可用于 Distant Stars DLC 已启用。 |
A random system in the galaxy with a Gaia World and another habitable world will be home to the Tiyanki Matriarch, the eldest member of the species and the only one to be aggressive when approached. The Matriarch has two weapons - one that ignores armor and does -75% damage against shields and one that deals double damage against both shields and armor. It also has significant armor and very high hull but no shields and as a result should be engaged with energy weapons.
Defeating the Tiyanki Matriarch gives the following rewards:
- Reth Unddol, a level 5 admiral with the unique
地狱雄心 trait.
Genocidal empires will kill him for 120-350 凝聚力 instead. - AH4B, a battleship that can be used or scrapped for 1500
矿物 . It comes equipped with the following components:
| Weapons | Utility | Core |
|---|---|---|
|

The Voidspawn is an unborn guardian, hidden within a size 20 
Dry world orbiting a class G star. Within a year after colonizing a planet in the system, an event will mention how the dry world has a pulse. Within the next half a year the planet will change its appearance, add 30 
The Voidspawn uses only guided weapons. It has high hull and armor but no shields, making energy weapons effective against it. Defeating the guardian grants 600-6000 
Gargantuan Evolution technology.

|
只可用于 Distant Stars DLC 已启用。 |
A random class M Red Giant star system will contain an ancient battlefield debris field patrolled by the Scavenger Bot, an ancient construct constantly scrounging the debris field for new parts.
The guardian uses only guided weapons. It uses equal amounts of shields and armor but has no point-defense and barely any evasion, making both guided weapons and strike craft very effective against it.
Defeating the Scavenger Bot grants the 
Nanite Repair System technology, as well as two random 
tier V component techs or a large amount of Engineering research if all techs were already researched.
Additionally the system has two broken worlds that bring in total 20
Shard
 |
只可用于 Ancient Relics DLC 已启用。 |
Shard is a guardian that fights identically to the Ether Drake. She appears upon the conclusion of the 
Kleptomaniac Rats Archaeology Site excavation. Defeating her grants the 
Rubricator Relic.
If the Relic World is colonized the Shard will destroy the colony in two years if she's not defeated.
As the excavation already requires claiming the system, the starbase can be upgraded into a bastion citadel in preparation for the fight. Alternatively the final Chapter of the site can be delayed to better prepare technologically.
If Shard spawns adjacent to a Fallen Empire, the Empire will send a fleet to destroy her, rendering the Rubricator unobtainable.

Between 6.5 and 13.5 years after the the game has started the owner of the system will get a notification that the Sky Dragon is hungry and be given the option to let it land on the capital, refuse or observe.
- If refused the Sky Dragon will kill 2 pops and add two blockers on the capital.
- If observing the Sky Dragon will kill 1 pop and then feed.
- Allowing it to land costs 75
影响力 and the Sky Dragon will feed.
Feeding the Sky Dragon takes 14-16 years, during which the capital will gain the 
Feeding Dragon planetary feature. When feeding is complete the empire will be given a reward to choose between a small amount of
If the system owner researches at least 2 Engineering technologies during the first 13-49 years it will gain the option to issue one of two special projects:
- Remote Dragon Scanning special project grants a moderate amount of
社会学研究 research. - Dragon Specimen Gathering special project brings the following outcomes:
- 30% chance the science ship and scientist are destroyed and the project can be attempted again with a different outcome
- 55% chance the project can be attempted again with a different outcome
- 15% chance the project succeeds and the empire will unlock the next
armor technology. - If the project is attempted a second time there is a 75% chance the Sky Dragon will kill 2 pops and add two blockers on the capital. The chance is reduced to 25% if the dragon was fed. If this second attempt is successful, gain 50% of the science cost for the next armor technology instead of 100%.
After either special project has completed and the empire has established communications with at least 70% of the galaxy a first contact will be established with the Sky Dragon. Finishing the first contact grants 150
After establishing first contact with the Sky Dragon, and picking 6 ascension perks, or 4 ascension perks including a phase 2 ascension path perk, the guardian will ask the empire to help raise its children. Refusing will grant 500 
Dragon Hatchery starbase building.
An empire that kills the Sky Dragon will gain access to the Dragonslayer trait.
The Sky Dragon uses only energy weapons and armor and as a result ships equipped with shields and energy weapons are the ideal counter.
