UNSC Rubicon

The UNSC Rubicon was a UNSC Navy vessel, employed by the Office of Naval Intelligence on a classified mission to Installation 00.

History
During a scouting mission to the ruins of Installation 00, UNSC operatives were pinged by a Forerunner signal. In response, the Rubicon was deployed to the area from Luna, carrying specialist remote contact teams and ONI scientific personnel. Due to the damage dealt to the Ark's life support systems, the RCTs were forced to brave extremely hostile conditions on the surface in search of the signal's origin. Contact was lost with all teams after eight days; only RCT-06 returned with heavy casualties. However, they succeeded at recovering the beacon's source - the remains of 343 Guilty Spark himself.

The science team questioned the damaged monitor on his origins, who obliged the humans due to their authority as Reclaimers. Over the course of the interrogation, Spark breached the Rubicon's firewall several times, much to the team's dismay. Spark powered down after concluding his story and was subsequently ejected into space; unknownbest to the crew, he has already transferred himself over to the shipboard computers. After subduing the onboard AI and taking control of the ship, he explained to the crew that he will resume his quest to find the Librarian and retrieve the spirits of his old friends, Riser and Vinnevra. Asserting that the Librarian is still alive, he put the crew to sleep and had the Rubicon proceed to her location.

Search-and-rescue teams was sent to the area after contact with the Rubicon was lost, but they failed to find any trace of the ship.
