The Moon Pool is a fantasy novel by Abraham Merritt (1884-1943). It originally appeared as two short stories in All-Story Weekly: "The Moon Pool" (1918) and its sequel, "Conquest of the Moon Pool" (1919). These were then reworked into a novel released in 1919. The protagonist, Dr. Goodwin, would later appear in Merritt's second novel, The Metal Monster (1920).Although Merritt did not invent the "lost world" novel—he followed in the footsteps of Bulwer-Lytton, Conan Doyle, Burroughs, and others--this work extended the tradition. The plot concerns an advanced race which has developed within the Earth's core. Eventually their most intelligent members create an offspring. This created entity encompasses both great good and great evil, but it slowly turns away from its creators and towards evil. The entity is called either the Dweller or the Shining One.Eventually of the race which created it, only three are left; these are called the Silent Ones, and they have been 'purged of dross' and can be described as higher, nobler, more angelic beings than are humankind. They have also been sentenced by the good among their race to remain in the world, and not to die, as punishment for their pride which was the source of the calamity called the Dweller, until such time as they destroy their creation--if they still can. And the reason they do not do so is simply that they continue to love it.
