0 appearances

Purpose

Regulate pressure in the Gravitron's gravitational field, enabling full activation as ordered by Cybermen

Significance

Expose Cybermen's operational weakness—they depend on human puppets to run the Gravitron, avoiding its gravity hazards themselves; ramping pressure advances their Earth invasion while the Doctor exploits this flaw
