chunk: 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 creationâif they still can. And the reason they do not do so is simply that they continue to love it.
