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.

The Metal Snake-Root is Exxilon’s automatic defense system, an abiotic entity engineered from submerged metal and mineral deposits. When the rogue planetary city activates its defenses, this creature emerges from flooded corridors with predatory efficiency, killing any perceived threat—Exxilons, humans, or Daleks—without discrimination. Its movements blend mechanical precision with organic predatory instinct, striking from concealment before vanishing back into subterranean waters. The creature embodies the city’s relentless sovereignty, executing lethal enforcement through sheer force rather than intelligence.
