31 Days of Monsters: Day Twenty-three — A Morlock

In H.G. Wells' "The Time Machine," the protagonist travels to the far future and finds the world radically changed. He encounters two offshoots of the human race: The docile, childlike Eloi and the cannibalistic, subterranean Morlocks. The Time Traveler deduces that the Morlocks are the descendants of the working class, who were forced to toil underground by the ruling class. Over time, the ruling class became less and less able to fend for themselves, becoming more dependent on the workers. Eventually society collapsed altogether, and the workers, now adapted for life in darkness underground, began to farm their former rulers, the Eloi, as cattle.
