Primary Containment Facility

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
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.

Relics
A collection of eleven relics is kept in the Primary Containment Facility one of human origin, some of Precursor origin but most from other, unidentified alien species. Further information on these relics can be found here: Precursor Relics.

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
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. Fauna=

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, 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.
