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 {{iconify|Engineering}}, {{iconify|Physics}} or {{iconify|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 {{iconify|Gestalt Consciousness}} empires.

AI empires can also sell a discovered artifact to Player empires for 1000 {{iconify|Energy}}. If the Player empire has the {{iconify|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 {{green|Protective}}, {{green|Friendly}} or {{green|Loyal}} attitude will offer the artifact for free instead of asking for payment. Each AI  Empire will only offer an artifact once.

{{expansion|anr}}
Players can spend 25 {{iconify|Minor Artifacts}} to discover a 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 {{iconify|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 {{iconify|Minor Artifacts}}.

== Precursor civilizations ==
There have been 7 precursor civilizations, 2 of them requiring the {{iconify|Ancient Relics}} DLC.

== Archaeological sites ==
[[File:Archaeology Site.png|thumb|250px|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. The chance is reduced to 0.25% for 5 years after a site is 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 {{green|-25%}} if the Scientist on the Science Ship has the {{iconify|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.

==== Precursor sites ====
Precursor Archaeology Sites are visible only to the empire that starts the event chain and are used to advance the Baol and Zroni event chains. When a Zroni Archaeology Site is discovered the planet will gain a deposit of 2-4 {{iconify|Zro}}.

==== The Sentinels ====
The Sentinels is an Archaeology Site with slightly different mechanics. It can be discovered after a planet is colonized and adds an archaeological site blocker to the colony.

|}

When the site is completely excavated the empire will get the following choices:
* If not {{iconify|Xenophobe}} or {{iconify|Fanatic Xenophobe}} gain an {{iconify|Unity}} from Jobs planet modifier and a permanent blocker.
* If not {{iconify|Xenophobe}} or {{iconify|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 planet will be invaded by 9 armies. If the armies are defeated the colony will gain the [[File:D mineral fields.png|24px]] Sentinels planetary feature and empire will be offered to either gain 150 {{iconify|Influence}} or issue a special project to see what the Sentinels were guarding. Finishing the special project will bring the following options:
** Gain 300 {{iconify|Influence}} and the ''Cheap Thrills'' planet modifier that gives {{green|-10%}} {{icon|pop consumer goods upkeep}} Pop consumer goods upkeep and a {{green|+5%}} {{iconify|Happiness}}.
** Gain the ''The Evermore'' planet modifier that gives {{green|+10%}} {{iconify|Research}}.
** Gain access to the ''Replicate the Evermore'' special project.
** If {{iconify|Militarist}} or {{iconify|Xenophobe}} gain 300 {{iconify|Influence}} and access to ''Cheap Thrills'' planet modifier that gives {{green|+10%}} {{iconify|Militarist}} Ethics Attraction, {{green|+10%}} {{iconify|Xenophobe}} Ethics Attraction, {{green|-10%}} {{icon|pop consumer goods upkeep}} Pop consumer goods upkeep and {{green|+5%}} {{iconify|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, {{red|-2}} Clues
* Archaeology team members die, {{red|-1}} Clues
* A dangerous situation is avoided, {{green|+3}} Clues
* Choice to pay 100 {{iconify|Energy}} to get {{green|+3}} Clues or do nothing and get {{red|-2}} Clues
* Science Ship Scientist gains the {{iconify|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 {{iconify|Curator Archaeology Lab tech|24px}} 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.
