Exodus
Encountered by USS Daedalus in 2401 as part of the Fourth Fleets investigations into increased Borg signals, Exodus was the home of a group of Unimatrix Zero survivors following the Borg Collective's restructure caused by the release of the Neurolytic Pathogen.
When Daedalus encountered the vessel it was severly damaged as a result of its journey from Borg terretory, those aboard were considering abandoning the vessel
Service History
Service to the Collective
Constructed in 2375 at Unimatrix 325, the vessel began as Sphere 531 and was assigned a variety of obejctives in service of the collective. It was present in the Yontasa Expanse during the assimilation of several planetary systems and operated in an exploratory function at the edge of Turei and Malon territory.
Release from the Hive Mind
In 2378 the crew of USS Voyager released a neurolytic pathogen in the heart of the collective causing the apparent death of the Borg Queen and the desctruction of a large portion of the collective's internal functions. This pathogen seperated a substantial number of drones and vessels from the Hive Mind's control; where other drones fell into a state of confusion those drones with the genetic mutation that allowed them to retain their indentities within the hive mind (who had at one time formed Unimatrix Zero) found themselves fully released from the Borg control. By chance several of these Unimatrix Zero surivors were aboard Sphere 531 when the pathogen rendered the vessel imobile.
Journey to Starfleet
Following several attempts to make contact with other survivors by the small crew of the sphere, now named Exodus, they found another cluster of survivors aboard a deep space probe attempting to make repairs at the edge of Malon space. Following an attack by a Malon transporter the probe vessel was lost and the survivors joined Exodus.
