Morlock Night is a science fiction novel by K. W. Jeter. It was published in 1979. In a letter to Locus Magazine in April 1987, Jeter coined the word "steampunk" to describe it and other novels by James Blaylock and Tim Powers.
Personally, I think Victorian fantasies are going to be the next big thing, as long as we can come up with a fitting collective term . . . like "steampunks", perhaps...—K.W. Jeter[1]
Morlock Night uses the ideas of H. G. Wells in which the Morlocks of The Time Machine themselves use the device to travel back into the past and menace Victorian London. King Arthur and Merlin appear as England's saviors.
