Planetary Pyramid Fortress

Marinus Pyramid

This pyramid serves as the central stronghold on Marinus, housing the vital Conscience machine under Arbitan's lone protection. Its interior consists of narrow, shadow-cloaked corridors vulnerable to Voord infiltration, where Susan fights a frog-masked assassin and Ian later rescues Arbitan from another assassin. The pyramid's lethal mechanisms include shifting wall panels, acid pools, rushing water, and hidden traps (e.g., the slab that drops open beneath Susan and the Doctor, plunging them into darkness). The seamless stone walls of the pyramid conceal these traps, cutting off all light and sound once triggered. The structure's isolation and fragile defenses underscore the crew's growing entanglement in Marinus's dangers.
