History WMG / Subnautica

Specifically, it was a gate that linked the Primary Containment Facility's water-circulation system to a vent at 4546B's pole. Originally designed to pipe measured amounts of frigid polar water into the giant holding tank, easing the energy-expenditure of keeping such a habitat cool in the Active Lava Zone, it later became an alternate route for peepers to carry the Sea Emperor's Enzyme 42 out to the open sea. Unfortunately for the peepers, those which took that route didn't live long in the frigid waters they found themselves in, but even their frozen-to-death carcasses provided a source for the enzyme which Sector Zero's organisms could benefit from. Arctic life forms didn't enter the tank from the other side, because the warmth of the water from the outflow side of the vent alarmed them. Ryley never accesses the lower parts of the Primary Containment Facility's pipe network, so he never found this still-functioning gateway, and Robin never finds the vent it links to, because once the Sea Emperor died, the giant tank's water-circulation system shut down automatically, allowing the polar vent to become silted over and hidden.

[[WMG: Life in 4546B's polar region survived Kharaa because an open gate was left operational between the Crater and Sector Zero.]]

Marguerit claims to have had nothing to work with but a repair tool and a knife when she washed up in Sector Zero. Yet, by the time Alterra begins its operation there, she's had a functioning home base, greenhouse, Prawn suit, and numerous pieces of equipment at her disposal for years. As she wouldn't have been equipped to dive down to the ''Mercury'' wreckage when she debarked from the Reaper carcass, it's likely that she found the cave where the Sol vessel's captain had reluctantly opted to abandon her Kharaa-infected crew members, rather than risk bringing the infection back to human space. Although those castaways were already decades dead by the time she arrived, their equipment - including, most crucially, a fabricator - gave Marguerit the "starter" gear she needed to survive at more than a cavewoman level.

[[spoiler: Al-An was determined not to let Alterra discover him or loot the technologies of his people, and he spent most of ''Below Zero'' sharing headspace with a woman who loathed the company. He also felt bad about how 4546B's biosphere had suffered horribly from the Kharaa outbreak, and for how his research team had abused the old Sea Emperor and her unhatched offspring. Finally, he couldn't afford to let the Federation at large learn of his homeworld or exploit the phase gate that led there, because others of his kind might still be there, whether animate or downloaded, and vulnerable to potential invasion. So, in short time between Al-An's own passage through the transport arch and Robin's joining him, he linked into the remnants of the Architects' old communication network and ''reactivated the Enforcement Platform'' remotely, setting it to re-impose the quarantine immediately after he and Robin had departed. The next Alterra ship to come anywhere near 4546B will get a single warning shot, but that's all the concession he'll allow them: from now on, the planet's seas can belongs to the Sea Emperor's offspring, and its meager land, to Marguerit.]]
