Krotons' Machine (Including Structural Pillars)

A massive Kroton-controlled structure with three metal support pillars rising from the under-hall floor beneath the Learning Hall. Jamie McCrimmon enters this structure, raising fears he has been absorbed as a power source. The machine features a leaking power sphere, signaling vulnerability. The Doctor, Zoe, Thara, Vana, and Selris discuss sabotaging it with sulphuric acid, while the Doctor and Zoe later plot re-entry. The machine's structural pillars (identified by Selris) are a tactical target for undermining, aiming to collapse the machine and force the Krotons out. Destroying it before it escapes is critical to halt the Krotons and rescue Jamie.

Purpose

Absorbs high-intelligence individuals like Jamie as a power source; mobile enough to escape destruction.

Significance

Capturing Jamie inside forces the Doctor's group to prioritize rescue over Gond rebellion, exposes Kroton weakness via the leak, and pivots the mission to infiltrate and demolish it before escape, amplifying emotional stakes and tactical pressure.
