Samech suffers an endemic shortage of traditional power sources, having long ago consumed all its traditional fuel resources.
The core can convert biological matter into electricity, allowing the scavengers to subsist on corpses and vermin found amidst their salvage. However, transmuter cores are more efficient at converting living matter than dead. This has led to an unintended preference in the servitors to "feed" on the living rather than the dead. Units low on power often abduct victims to use as bio-sources until they expire.
