Planet 456B (Galactic Dom Lore)

Planet 456B is a ocean-based planet with a oxygen-nitrogen atmosphere where the ship Olpmy, Sunbeam, and the Degis crash-landed. It is a heavily untouched, undeveloped world with little structures, that only being the habitat stations of survivors of crashed ships and the bases of the ancient precursor race of the planet, the Winn, inhabited in.

Planet 456B is located in the outer reaches of the Milky Way Galaxy, orbiting around the star 4546. The “B” means that 456B was the first planet discovered around the star 4546 (or 4546A). It also harbors two moons, one being very close to the planet, causing frequent solar eclipses.

There are three known major ecosystems on the planet: the Crater, Sector Zero, and the Dead Zone, the latter of which covers the majority of the planet.

The known planet is almost completely covered in water, except for a few islands, and features a variety of submerged biomes. The Degis colony ship is located a few meters above the surface, in relatively shallow water.

The Crater features a full ecosystem of flora and fauna. However, this is only a very small area of the planet, located in one of many dormant volcanic craters of the planet, approximately 2km in diameter. The Arctic supports a nearly completely different ecosystem, harboring more creatures and plants adapted to the colder temperatures. The rest of the ocean is known as the Crater Edge, it is extremely deep and nearly devoid of life, supporting only microscopic life forms, and Leviathan Class Lifeforms. It is unknown whether any similar areas of life exist elsewhere other than the many craters of the planet and arctic.

Precursor Winn and PDA data from survivors make note of high thermal activity from the planet's core. This is evidenced by the Inactive Lava Zone and Lava Lakes, respectively. The Precursor Winn took advantage of this feature, installing the Alien Thermal Plant within the deep Lava Zone, which allowed the generator to harness the planet's natural thermal energy.

History of the Planet
The Winn around a thousand years ago from the crash of the Degis arrived at the planet, and set up the planet as a research base for the foreign Khar bacterium, setting up numerous alien bases there before abandoning it when the bacterium escaped their primary research faciality, the Disease Research Center (DRC) in a incident involving the primary anchors destabilizing after a large leviathan-class lifeform known as the Emperor Leviathan, escaped, damaging the faciality in the process.

Shortly before the last personnel of the Winn left the planet, they built a special gun platform, called the Quarantine Enforcement Platform on one of the islands of the planet to prevent any spaceships from exiting or entering the planet, thus preventing any offworld spread of the Khar bacterium. The platform was largely responsible for the crash of the Degis, Olpmy and Sunbeam spacecraft on the planet.

10 years before the crash of the Olpmy, the colony ark Degis crash-landed on a shallow section of the Crater, with the survivors of the crash eventually being infected with Khar bacterium and dying in the process or got killed by giant, hostile lifeforms known as leviathans or mysterious genetically engineered creatures equipped with a small warp mechanism that gave it the name of Warper. The Warper is a bio-mechanical lifeform with warp-engine capabilities, whereas it generates a warp-gate to warp itself in a way similar to spaceship warp-engines on Pandora to travel. According to the logs of the Winn, it seems that the Warper was designed by them to guard their facilities and kill any infected survivors of ships that crashed on the planet, preventing their escape.

Eventually, the last survivors of the Olpmy disabled the Quarantine Enforcement Platform after discovering the Emperor Leviathan inside the Disease Research Center and utilizing the ability of the creature's offspring to create enzymes that supposedly cures Khar bacterium-infected people. They managed to build a rocket to escape the planet shortly after. After the escape of the survivors, the corporation Alterra took interest in the vast resources of the oceans and islands of the planet, and agreed to jointly-operate with the Pandoran government in exploiting the scientific and resource value of the planet. The first colony ships, part of the Eckart Colony Fleet, landed on the planet's islands and shallow seas in February 2341, establishing a collection of frontier settlements inside the planet's Crater and Sector Zero ecosystems.
