Research and development
Argent Moon (ARGMN) was a research and development station in service with the UNSC Navy's Office of Naval Intelligence. Rooker served as the station's shipboard artificial intelligence in 2557.
Research and accident
Commissioned on February 13, 2546, it did not enter service with ONI until May 7, 2553, Argent Moon served as a top-secret research and development station for the Office of Naval Intelligence. The station's existence was known to only a handful of individuals, with ONI personnel experimenting with a variety of highly classified and experimental projects, as well as weapons testing. ONI crew aboard Argent Moon also experimented with technology retrieved from the Halo Array. The crew of Argent Moon were also experimenting with unsanctioned stealth technology.
In 2557, some personnel aboard the station created and experimented with Asteroidea, an unsanctioned biological weapon that remained dormant and asymptomatic as it spread through a population before it was activated by an otherwise harmless aerosol dispersal; all test formulas were tested on live Kig-Yar subjects. There were also unknown, misshapen creatures detained in the laboratory's tanks. In March 2557, an accident caused a particularly aggressive form of the biological agent to vaporize and spread throughout the station via its air systems, killing nearly all aboard. Those closer to the accident were killed instantly and, depending on distance from the accident, the rest of the vessel's personnel began suffering symptoms from the chemical minutes or hours later. Although shipboard smart AI Rooker attempted to enforce quarantine protocols, they "massively" failed and all personnel aboard Argent Moon were dead by March 17, 2557. As a result, ONI lost contact with Argent Moon and Rooker sent a message that warned any ONI personnel who board the station of the situation. Rooker then took further actions to quarantine the vessel; he put Argent Moon on a course that kept it away from all inhabited systems and jettisoned what remains he could into open space. On September 12, 2557, Rooker was now suffering from rampancy due to being six months past his "expiration date". Feeling he could no longer manage the vessel, he initiated his own destruction.
Raid on Argent Moon
- Main article: Raid on Argent Moon
In October 2558, nineteen months after it went missing, Argent Moon was discovered by Kig-Yar scavengers, who sold it to Jul 'Mdama's Covenant. Preparing for an attack on Sanghelios, the Covenant infiltrated the station in search for weapons and resources to use against the Swords of Sanghelios. One week later, Spartan-II Blue Team was tasked with securing the vessel and its intel, encountering the Covenant scavengers aboard the vessel. Unable to secure Argent Moon due to the scale of the Covenant occupation, Blue Team was forced to overheat the station's reactor, destroying it along with several nearby Covenant warships.
Due to the station's obscurity, UNSC investigators who examined the remains of Argent Moon were unaware of the station's role. The investigators searched the debris for clues, and eventually discovered that the station's crew were manufacturing bioweapons.
The design of Argent Moon loosely resembled that of some deep survey craft designs of the 22nd century. The station is equipped with maneuvering propulsion systems at the aft that allow Argent Moon to travel through space, though Argent Moon is still classified as a large-scale production plant rather than a ship. With propulsion systems at its aft and navigation and operation controls at the fore, production and experiments on Argent Moon occur in the center of the station, within a massive, city-sized superstructure. Argent Moon was an ONI research and development vehicle that went missing. In addition to its secretive nature, the station's hangar bays housed at least one Winter-class prowler and a stealth corvette.
