Revenant

Revenants were reanimated corpses of the dead, controlled by chips in the cranium.)

When visiting an unnamed planet in the Angelo Spiral to collect her bounty after assassinating Berkley Silver, Vienna Salvatori and her hostage Norvelle Spraggott came across the dead crew of a research base who had been reanimated as revenants.

When on the planet Volcana, Roxanna Ceverley informed Vienna that Berkley Silver had taken refugees from the Wrath Empire, murdered them and had converted them into revenant slaves. (AUDIO: The Memory Box)
