This article is for the PC version of Stellaris only.
First League anomaly

The Precursors are long dead galactic empires predating even the fallen empires and the curators. Their ruins are scattered across the galaxy for the player to find via anomalies or archaeology sites. Precursor anomalies grant a special project which once investigated grants a small amount of Engineering research Engineering, Physics Research Physics or Society research Society research as well as a precursor artifact. 6 artifacts are required to reveal the location of a precursor's home system.

If every precursor anomaly has been investigated but no empire managed to collect 6 artifacts a random event can trigger every 20 years and add another precursor anomaly on one of the previously investigated planets. The time is lowered to 13.3 years for Gestalt consciousness.png Gestalt Consciousness empires.

AI empires can also sell a discovered artifact to Player empires for 1000 Energy.png Energy. If the Player empire has the Civic warrior culture.png Warrior Culture civic it can threaten the AI empire to surrender it for free, the success rate depending entirely on both empires' Relative Power. Empires that hold a Protective, Friendly or Loyal attitude will offer the artifact for free instead of asking for payment. Each AI Empire will only offer an artifact once.

Players can spend 25 Minor artifacts.png Minor Artifacts to discover an precursor site with a cooldown of 5 years.

Once a Precursor homeworld has been discovered the empire will gain an artifact action to spend 50 Minor artifacts.png Minor Artifacts to start a special project to delve into the secrets of one of the Precursor civilization. Finishing the special project will grant a permanent empire benefit. If the DLC is installed precursor anomalies will also grant 1-5 Minor artifacts.png Minor Artifacts.

There have been 7 precursor civilizations, 2 of them requiring the Ancient Relics.png Ancient Relics DLC.

Archaeological sites

Archaeology Site

Archaeological Sites are areas where remains of ancient civilizations have been preserved relatively intact. They can be discovered while surveying, generated at game start or uncovered a few years after a planet is colonized. Each time a planet is surveyed there is a 1.25% chance of an archaeology site being discovered.

A site can have 1-6 Chapters in addition to an introduction Chapter. Each Chapter has its own narrative and rewards and has to be unlocked before it becomes visible. Chapters are unlocked via Excavation. As long as an Archaeological Site is within an empire's borders that empire can task a Science Ship to excavate the site. The duration of an Excavation is determined by the Archaeological Site's Difficulty rating and can be reduced by −25% if the Scientist on the Science Ship has the Leader trait archaeologist.png Archaeologist trait. As the Scientist goes through excavations, it will generate a random number from 1 to 10 and add modifiers to the result, with the following formula: Result = dice roll + archaeology skill + clues − difficulty. Additional events can also trigger at the end of each excavation.

From Gateway Sent

The From Gateway Sent Archaeological Site is discovered by investigating the special project created by the Origins gateway.png Galactic Doorstep Origin.

The Origins one the shoulders of giant.png On the Shoulders of Giants Origin adds a lengthy Archaeological Site chain in the empire home system. The narration of the last two chapters of the final site are random but the rewards are always the same.

The Sentinels

The Sentinels is an Archaeology Site with slightly different mechanics. It can be discovered after a planet is colonized and unlike all others it brings a choice when completely excavated. When discovered it adds an Archaeological Site blocker to the colony.

Tile Blocker.png Archaeological Site blocker removed

When the site is completely excavated the empire will get the following choices:

  • If not Xenophobe.png Xenophobe or Fanatic Xenophobe.png Fanatic Xenophobe gain an Unity.png Unity from Jobs planet modifier and a permanent blocker.
  • If not Xenophobe.png Xenophobe or Fanatic Xenophobe.png Fanatic Xenophobe issue a special project to open the Sentinels. When the special project is complete the empire will have the option the hear the Sentinels or attack. Attacking will have the Sentinels invade the colony with 9 armies. Hearing them out will bring the option to either gain a permanent blocker and 9 defense armies or be hostile and have the Sentinels invade the colony with 9 armies. The invasion has an Army Strength of roughly 2400.
  • Issue a special project to destroy the Sentinels. When the special project is complete the will be invaded by 9 armies. If the armies are defeated the colony will gain the D mineral fields.png Sentinels planetary feature and empire will be offered to either gain 150 Influence.png Influence or issue a special project to see what the Sentinels were guarding. Finishing the special project will bring the following options:
    • Gain 300 Influence.png Influence and the Cheap Thrills planet modifier that gives −10% Mod pop consumer goods mult.png Pop Consumer Goods Upkeep and a +5% Mod pop happiness.png Happiness.
    • Gain the The Evermore planet modifier that gives +10% Research.png Research.
    • Gain access to the Replicate the Evermore special project.
    • If Militarist.png Militarist or Xenophobe.png Xenophobe gain 300 Influence.png Influence and access to Cheap Thrills planet modifier that gives +10% Militarist.png Militarist Ethics Attraction, +10% Xenophobe.png Xenophobe Ethics Attraction, −10% Mod pop consumer goods mult.png Consumer Goods Upkeep and +5% Mod pop happiness.png Happiness.

Excavation events

If at the end of an Excavation phase the result is not high enough to grant a Clue or finish the Chapter then one of the following events may happen:

  • Science Ship Scientist dies, −2 Clues
  • Archaeology team members die, −1 Clues
  • A dangerous situation is avoided, +3 Clues
  • Choice to pay 100 Energy.png Energy to get +3 Clues or do nothing and get −2 Clues
  • Science Ship Scientist gains the Leader trait maimed.png Maimed trait


Excavation time

Assuming you never get any of the aforementioned events, the average number of rolls required to complete the chapter can be read from this table. "S + C - D" is the scientist's archeology skill, plus clues, minus difficulty. A level 3 scientist with Tech archeology lab.png Curator Archaeology Lab tech researched and 2 clues, excavating a level 4 chapter, would have an S + C - D of 5 + 2 - 4 = 3, and will need slightly under four and a half more rolls, on average, to complete the chapter.
