Mondas

Dying homeworld of the Cybermen, distinct from the Cyberman Invasion Ship. Mondas is a planet-scale entity whose disintegration severs the Cybermen's power link, forcing their retreat. It is observed via radar screens and described in cosmic terms (e.g., 'brightening and darkening like a faltering sun') but is never a setting for direct character interactions. Its collapse is a narrative catalyst, not a physical location.

S4E6 · The Tenth Planet Part 2
Wigner orders global defense mobilization

Mondas, though not physically present in the scene, is a critical location referenced throughout the dialogue. It is described as the origin of the Cybermen and the site of the stranded astronauts Schultz and Williams. The planet’s hostile environment and the Cybermen’s dominance there are implied, framing it as a symbol of humanity’s existential threat. The revelation of the lone astronaut mission to Mondas underscores the planet’s role as a battleground and a target for Earth’s counteroffensive. Its mention in the scene reinforces the stakes of the conflict and the desperation of Earth’s response.

S4E8 · The Tenth Planet Part 4
Cutler’s Collapse and Cyberman Takeover

Mondas is referenced through Lieutenant Cutler's garbled transmission and the Doctor's warnings about its impending disintegration. Though not physically present in the scene, Mondas looms as an ever-present threat, its erratic energy fluctuations and approach toward Earth driving the Cybermen's desperation. The planet's fate is tied directly to the humans' actions, as the Cybermen seek to drain Earth's energy to save it. Mondas serves as a reminder of the cosmic stakes at play, where human lives are mere pawns in a larger, inevitable tragedy.

Atmosphere

Erratic and unstable, with Mondas' surface brightening and darkening like a dying star. The transmission describes it as a 'switchback,' unpredictable and faltering, reflecting the desperation of the Cybermen and the futility of their invasion.

Doctor Negotiates with Krang

The Radiation Room is mentioned as the designated location for relocating the warhead, chosen by Barclay for its depth and safety. Though not yet physically entered in this event, its role is critical: it will serve as the temporary storage site for the disarmed warhead, bought time for Mondas to collapse, and a potential refuge for the group. The room’s isolation and radiation hazards make it a high-stakes location, where the group’s actions will determine the fate of Earth.
