Eden Concealment Rock

A roughly hewn limestone fragment half-buried in the Eden projection's underbrush, its gray surface streaked with vein patterns. The Doctor and Romana press their bodies against its irregular edges as the Mandrel's snuffling passes, their breath slowing to silence. Stott later spots another unused fragment where the second Mandrel had lurked, noting the creature's camouflage tactics. Its lack of distinct features reinforces the Eden landscape's synthetic nature.
