Doctor reveals Zanak’s planet-devouring nature

The Doctor shatters the Mentiads' confusion by exposing Zanak as a hollow planet hijacked by vast transmat engines that expropriate other worlds’ matter and energy. Romana clarifies each step of the process—vanishing, rematerialising, smothering and mining—while Mula and Kimus absorb the horrifying mechanics of a predatory cosmic leech. What begins as an abstract search for understanding crystallises into shared horror as the companions grasp the Captain’s method: entire planets are obliterated to feed a grotesque system of control.

The Doctor targets the hideous mechanism itself during explanation, using it as a pedagogical exhibit—the engines are not merely hidden but placed beneath a symbolic mountain, tying the revelation of their predation to a literal and moral topography. Romana invokes them as agents of planetary vanishment, recasting them from background to active villain.
