A Void Droid represented a droid without an owner that had deteriorated due to inadequate upkeep and faulty programming, ultimately leading to its mental instability. Often, Void Droids would coalesce with other malfunctioning droids, creating mobile packs. These groups were compelled to scavenge and pilfer both power and spare components for their continued existence; in some instances, Void Droids would even resort to violence against ordinary droids in a desperate search for lubricant and other essential components. The remnants of starships and space stations were commonly linked to Void Droids. A particular assembly of these droids made their home within a fragment of debris originating from the Galactic Empire's annihilated Death Star battle station following the Battle of Yavin. Prior to 2 ABY, these droids encountered a team of Alliance to Restore the Republic operatives and their Squib guide.
