Goth (planet)
From Tardis Wiki, the free Doctor Who reference
Goth was the bleak planet of the Deathsmiths. It held their weapons cache. 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.
