Oleth

Oleth, known in the old ages as Pluto, is the eight 'planet' from Archangel.

Features
Though its nature is still debatable, Oleth is considered by many to be the true eighth planet in the solar system following Neaven's annihilation. It is estimated that Oleth may become habitable once Archangel's habitable zone expands to it, but for now, it is a frozen, barren wasteland. Numerous alien specimens trapped beneath the ice have been discovered, and are beginning to awaken. The only human presence outside of the occasional scavenger or unlucky shipwreck survivor is the Hades Research Base, though they have recently disappeared, as with most humans who set foot on Oleth.
