Deathsmiths of Goth

The Deathsmiths of Goth, expert weapons designers, were once more feared than the Daleks.

The Daleks acquired weapons from them during their battle against the Time Lords in the Last Great Time War. (DWA: 2006 Doctor Who Annual)

On their home planet of Goth, they created a superweapon known as the Apocalypse Device, however, this creation of theirs went out of control and began killing them. In an effort to contain this weapon, the Deathsmiths destroyed all starships on the planet leaving the Apocalypse Device stranded on Goth where it remained among the ruins. (DWM: Black Legacy)
