Dalek (Seasons of Fear)

A Dalek was deposited at a fort in Roman Britannia of 305 AD due to time travel experiments, (AUDIO: The Time of the Daleks) where it proceeded to engage the soldiers, who referred to it as a "metal demon", stationed there in a brief skirmish before being quickly overwhelmed and killed. (AUDIO: Seasons of Fear) Rumours of this metal demon persisted and were recorded by historians. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe)
