Overview: When the Cybermen arrive on Goth, desolate homeworld of the once mighty Deathsmiths of Goth, they want only to find weapons to make them the mightiest force in the galaxy. But Goth is not quite the dead world they expected, and something evil and unstoppable lurks nearby, something with the power to drive the Cybermen mad with nightmares and visions, and reduce their metal skins to rust. As Commander Maxel’s forces dwindle, he must face the unknown horror and stop it once and for all.
