Metal Snake-Root

The Metal Snake-Root is the planet Exxilon’s automated defense system, an abiotic creature engineered from metal and mineral deposits within the planet’s subterranean waters. Activated by the rogue city’s planetary consciousness when unauthorized factions enter its domain, this entity acts without discrimination to eliminate trespassers—Exxilons, humans, and Daleks alike. Its movements are swift and violent, striking from flooded pools to kill perceived threats before retreating. Though seemingly primitive in behavior, its purpose is singular: enforce the city’s sovereignty through lethal force.
