Cybernetically augmented humans – Cybermen – have emerged from the spacecraft to take control of Snowcap Base. Their world, Mondas, was thrown out of its orbit around the sun long ago, forcing its inhabitants to turn to cybernetics to preserve their species. Now, having succumbed entirely to the machinery that was only intended to extend their lives, the Cybermen face another kind of extinction. Mondas is a dying planet, and the Cybermen hope to colonize Earth for its resources – and its population – starting with initiating a transfer of Earth’s energy to Mondas.
