Outriders

The Outriders are a faction of human migratory refugees active during the Human-Covenant War. Largely made up of Arcadian colonists that survived the glassing of their homeworld, the Outriders' believed that any armed resistance against the Covenant was doomed to fail, and their only chance at survival laid in emigrating far away from the Human Sphere and known space. Unlike many insurgent movements, the Outriders preferred non-violent methods to achieve their goals, usually revolved around the theft of ships, supplies, and war material necessary for their long journey. However, as seen with the Cheriton's Viper Incident, desperation could see them taking up arms to achieve their aims.

Although most of their convoys were stopped by the UNSC and planetary defense forces, at least one major Outrider fleet was able to escape into deep space, beginning to head spinward up the Orion spur of the Milky Way galaxy. Whether the Outriders were able to settle a world and, if so, whether the colony was successful are unknown. No Outriders have since made known contact with the UEG to date, and it is likely any surviving colony that does exist will likely refrain from making contact with humanity for fear of triggering a Covenant attack. The possibility of stumbling upon such a world is a possibility plaguing the emerging diaspora into the spinward regions of the Orion arm.
