Darke (The Krillitane Storm)

Captain Darke was a local soldier and Captain of the Guard at Worcester in 1140. He aided the Tenth Doctor in his efforts to stop the farming of Krillitanes for their oil, in order to sell it to the highest bidder for personal genetic manipulation. He was the one to kill the 'Krillitane Storm' (A Krillitane mutated into a gigantic dragon-like creature against its will) itself, by using a highly concentrated solution of the oil, which was extremely toxic to the Krillitanes. He had lost faith in God, but still believed in the Devil, of whom he believed the Storm to be a servant. (PROSE: The Krillitane Storm)
