An Arbiter Class doll is a Recollection officer specializing in combat and enforcement.

Because of the Zaleri Research and Preservation Institute’s doctrine of pacifism, an Arbiter’s enforcement authorizations are limited to peacekeeping and security.

As specialized combat dolls, Arbiter Dolls are outfitted with a special void-leyline regulation engines which can temporarily attenuate the destructive effects of Entropic Degeneration Syndrome, which allow them to wield Void Artefacts.

However, the attenuation mechanism of Arbiter-class engines merely re-distributes residual void energy emanating from the Void Artefacts, rerouting entropic decay away from the doll core into the entire body. As a pertinent side-effect, Arbiter-class dolls have a drastically shortened operational lifespan.
