"Planet Aether, home of the Luminoth, was struck by a “Phazon Meteor” five decades ago. The impact had catastrophic effects on the already unstable planet, creating a “dark twin” of the planet and a fierce race known as the Ing. A brutal war between the twin planets took place, with the Ing gaining the upper hand. The G.F.S. Tyr went to the sector to investigate pirate activity, but were forced to make an emergency landing on Aether. Shortly after, the entire crew of Tyr was attacked and annihilated by the Ing. Hunter Samus Aran was sent to investigate, and wound up entangled in the local conflict. Aran fought against both Space Pirates and Ing, and arose victorious. Aether’s “dark twin” vanished, taking with it the Ing horde, and the planet’s peace was finally restored.
After the Aether incident, the Federation sent the G.F.S. Anhur back to Aether to deal with the pirate base. Upon arrival, the crew and marines of the Anhur assisted the native Luminoth in dismantling an abandoned Space Pirate mining facility. During the operation, the crew detected the presence of Phazon. The ship’s crew investigated and collected several kilograms of ore, which would later lead to the development of the PED."
