The Primary Containment Facility (PCF), also known as the Emperor Containment Facility or Sea Emperor Prison or merely the Prison, is an in-development Precursor Base located within the Active Lava Zone that will serve as the final major story location. It was built by the Precursors around one thousand years ago and is where the last Sea Emperor Leviathan is contained, along with the five remaining Sea Emperor Leviathan Eggs. There are two entrances to the cavern containing the Facility; located at -300 -1270 -150 and 90 -1240 360, southeast and directly north of the Lava Castle, respectively.

The Primary Containment Facility will require the Blue Precursor Artifact to unlock, which is found inside the Precursor Thermal Power Generator.

The Primary Containment Facility, like the other Precursor Bases, was built a little under one thousand years ago. It was purpose-built to contain the Sea Emperor Leviathan after it was discovered that it was immune to Carar. The aquarium section was originally all inorganic with several teleporter hubs set up (though none large enough to allow the Sea Emperor Leviathan's escape). However, as creatures began migrating into it, they brought with them flora seeds along with loose sand and mud. Over time, the aquarium became a thriving ecosystem with the Sea Emperor Leviathan at the heart. At an unknown date, the Sea Emperor Leviathan laid five eggs, which the Precursors took and placed in the Incubator Device to stimulate the hatching process as it was deduced that the young would be a more viable source of the cure, rather than their parent who was weak. But the aquarium was not a suitable environment for the eggs to hatch which was built to match the ideal environment for an adult Sea Emperor Leviathan, which differ from the ideal conditions for a juvenile Emperor, causing the eggs to go into a form of natural stasis for a seemingly indefinite amount of time, kept alive by the incubator. Numerous Ion Crystals will be found here.

Antechamber

"Antechamber"

The first room in the Primary Containment Facility. It is huge and roughly octagonal in shape. A large pillar lies in the center of the chamber it will be used to create Ion Crystals. Around this pillar are cases containing the Precursor Relics, six on each side. There are six doorways around the side walls of the Antechamber, four leading to teleporter rooms the other two leading to the "Pipe Room" and "Egg Room". Above the entrance another doorway can be found and accessed by ramps on either side of the entrance, this door leads to the "Baby Experiment Lab". At the far end of the Antechamber is another door that leads to the Moonpool Room. The Antechamber also has many specimen cases containing artifacts the Precursors collected, most originating from other alien races.

Artifact Data Bank Entries

These entries are from various artifacts kept in the Primary Containment Facility some of human origin, some of Precursor origin and some from other, unidentified alien species. <tabber> Alien Relic 1=


This alien device appears to be designed to eliminate all organic substances in range by emitting a lethal, but contained radioactive field.

|-| Alien Relic 2=


This device is some form of communications relay, apparently projecting the presence of the user to a remote location. There do not seem to be any other devices in range.

|-| Alien Relic 3=


This device is a rudimentary version of the keys used to access these facilities. It may have been kept here for symbolic purposes, or legacy support.

|-| Alien Relic 4=


It is unclear why technology of this sophistication has not been found elsewhere on the planet. Its production may have been restricted, or too costly, or it may have been pillaged from a more ancient civilization.

|-| Alien Relic 5=


This carving is hundreds of thousands of years old, and made from an unrecognized natural fiber, likely grown on an as yet undiscovered planet.

|-| Alien Relic 6=


Despite its simple design, this device contains enough potential energy to destroy the entire planet, and most of the solar system. Fortunately, it has malfunctioned.

|-| Alien Relic 7=


This weapon appears to be millions of years old, and matches no previously encountered technologies.

|-| Alien Relic 8=


An ancient earth blade, dated back to the 13th century Mongolian empire. Blood samples on the blade match the DNA of seven separate heads of state from the period.

|-| Alien Relic 9=

This rock-like material features bio-mechanical parts that match components identified in the warpers encountered on 4546B. Materials such as this may even have been a fundamental building block of the alien's own self-repairing mechanisms.

|-| Alien Relic 10=

The markings on this device seem to serve no purpose beyond decoration. It may be the alien equivalent of a lamp or magnifying glass, used to examine the other relics in more detail.

|-| Alien Reliquary 1=


This case is composed of an impregnable, translucent metal at the distant end of the periodic table. Scans do not reveal any contents.

|-| Alien Reliquary 2=


This case contains highly sophisticated nanobots capable of infiltrating a foreign body and deconstructing it from the inside.

Moonpool Room

A large room accessed through a door at the far end of the Antechamber, the main point of interest in this room is the large moonpool from which it draws its name. The moonpool leads to an observation platform above the Sea Emperor Leviathan's Aquarium where the player will encounter the Sea Emperor Leviathan for the first time. At the far end of this room is a doorway leading to a teleporter, which links to a teleporter in the Aquarium.

Aquarium

"Sea Emperor's Aquarium"

The main feature of the Primary Containment Facility, a huge aquarium containing the Sea Emperor Leviathan and the five Sea Emperor Leviathan Leviathan Eggs. The Aquarium is teeming with life; schools of fish, coral, grasses and Flora being scattered all around, some parts of the Aquarium resemble the Grand Reef and it also has small cave systems. Many large pillars made from the same material as Precursor Bases can be found running in two lines, parallel to each other in the middle of the Aquarium. Atop these pillars are drillable Ion Crystals, six in total. The Egg Incubator is found in a large hollow in the ground surrounded by small mounds of rock amongst which the Emperor will nestle itself whenever the player gets close to the eggs. There is a teleporter directly behind the Incubator, which goes one-way to the Quarantine Enforcement Platform. A teleporter leading back up to the Moonpool Room and another teleporter leading behind the Aurora can be found in the Aquarium. <tabber> Fauna=

Other Data Bank Entries

<tabber> Leviathan Egg Casing=

Shell Composition: The shell casing is formed from thick layers of carbon-composite, suggesting an extensive gestation period. This leviathan species may give birth just once per century, perhaps just once in their lifetimes.

Shell Casing Incisions: Precise incisions suggest a laser-based tool was used to cut open the egg casing and forcibly remove the fetus inside, prior to full gestation.

Analysis: - Time-pressure to develop a bacterial vaccine may have driven the alien researchers to cut open this egg and remove the fetus for study - It is also possible that, removed from its parent and natural habitat, some vital condition for the infant to hatch naturally was not met

|-| Aquarium Warpgate=


Scans indicate this warp gate has not been active since the facility was abandoned. It likely served as an access point to the surface of the planet. It is much too small for the emperor specimen to pass through, but may accomodate a juvenile specimen.

|-| Pipe Access Point=

This appears to be one of the endpoints of the alien piping system transporting fresh water from the surface into the containment facility.

- Peepers are using the pipe network to travel to and from the surface - Behaviour must be explained by evolutionary adaptation to extreme circumstances

|-| Dissected Leviathan Fetus=

Background: - Superficial damage to the specimen indicates it was forcibly removed from its egg-casing - The fetus appears to have been terminated for dissection immediately on removal - Cryogenically preserved

Bacterial Vaccine Potential: - Analysis of digestive system enzyme production indicates potential for full vaccination against effects of alien bacterium - However the fetus had not fully completed gestation - internal organ development is insufficient for enzyme production

Analysis: - A healthy infant specimen may be able to produce the enzymes necessary for a full vaccine against the bacterium - Given the specimen's potential, it is unlikely the alien researchers would have forcibly removed it prior to full development if they had discovered any way to hatch it naturally

Recommended Steps: - Unclear

|-| Peepers Exiting the Facility via Pipe Network=

These outflow pipes are transporting peepers out of the facility, back towards the surface.

- All specimens scanned are carrying the enzyme which inhibits bacterial growth and helps the body repair the symptoms of the infection - Stomach cavities are all empty

|-| Peepers Accessing the Facility via Pipe Network=

These inflow pipes are being used by peepers to access the otherwise isolated facility.

- Peeper behaviour elsewhere on the planet suggests they are not being sucked in by accident, but rather have evolved to actively seek out the correct access points - The specimens scanned have all consumed high quantities of seeds from the surface world - Specimens show differing levels of bacterial symptoms

|-| Alien Pipe System=

An access point to a deep, alien piping network that extends beyond maximum scannable range.

- The pipe is drawing in water from the surrounding area and pumping it to an unknown location below the surface - Peepers have been observed entering and exiting the access point - Other small creatures appear to be avoiding the vicinity - Purpose unknown

Assessment: Further data required

Future Plans

The antechamber will contain an airlock and various teleporters to different biomes and the other Precursor Bases - the receivers for these teleporters will be found scattered throughout the world.
The large, central, column of light seen in the Antechamber concept art will function as an Ion Crystal fabricator,^[2] creating drillable Ion Crystals which can then be drilled by the player. The crafting recipe is currently unknown.
Various cutscenes and animations will be shown here, ranging from simple Sea Emperor Leviathan swimming animations to a dramatic final reveal involving the Sea Emperor Leviathan eggs. One cutscene will include the Sea Emperor Leviathan investigating the player when he first enters the aquarium, then swimming off after judging the player as harmless.
Warpers will warp into the aquarium and attempt to kill the player.
