The Dreadbringers were the military and enforcement arm of the Darksmith Collective. Their uniform consisted of dark armour with a black angular helmet and a cloak. Their battle armour had a built in life-support system capable of withstanding space or underwater environments. Their breastplate showed the dark crimson flame motif of the Darksmiths and they were armed with a long thin staff.
Their main transport crafts were architecturally stunning, like a giant cathedral constructed of pale bone-like stones, wood and metal supported on metal stilts. Known examples of the dreadnought class include the Adamantine, which was dispatched to Flydon Maxima in pursuit of the Tenth Doctor and the Eternity Crystal. (PROSE: The Depths of Despair)
