YED-4 is a Covenant term for a dimension in slipstream space. During the onset of the Great Schism on November 3, 2552, Zasses 'Jeqkogoee, the navigation officer of ORS-class heavy cruiser Incorruptible, noted the presence of anomalies of undetermined origin in YED-4 that may have an effect on the safety of the ship's immediate slipspace transition.[1]
