Goth (planet)
From Tardis Wiki, the free Doctor Who reference
Goth, the bleak planet of the Deathsmiths, held the weapons cache of that dreaded species. It included their ultimate weapon, the Apocalypse Device. Long after the Deathsmiths themselves seemed to have departed, a squad of Cybermen landed there. After the Apocalypse Device had in effect, dispatched them (the Cyber-Leader of the squad, Maxel destroying himself rather than re-locating the Device off-world), a group of Sontarans arrived.
