Prehistoric Earth (400 Million Years BC)

A barren primordial landscape representing four-hundred-million-year-old Earth, now the dry floor of the future Atlantic Ocean. The terrain stretches under a blood-red sky as a vast, windswept plain of hard-packed, brittle rock formations. Jagged ridges cut the horizon, their surfaces smoothed by aeons of unrelenting weather. The Doctor and his companions stand amid this dead world—the ground exposed long before the ocean would return, the air thick with howling wind that scours life from the land. Here, the skeletal remains of a Jagaroth derelict serve as the final monument to a doomed civilization, its husk a silent witness to extinction. No water flows, no life persists beyond the trio; only the crushing silence of prehistory lingers.
