Task: Question Generation
Input (English):  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.
The Dweller is in the habit of rising to the surface of the earth and capturing men and women which it holds in an unholy stasis and which in some wise feed it. It increases its knowledge and power constantly, but has a weakness, since it knows nothing of love. The scientist Dr. Goodwin and the half-Irish, half-American pilot Larry O'Keefe, and others, follow it down. Eventually they meet a woman, beautiful and evil, named Yolara, who in essence serves the Shining One, and the 'handmaiden' of the Silent Ones, beautiful and good, named Lakla. Both want O'Keefe and eventually battle over him.
There is also a race of very powerful and handsome 'dwarves' and a race of humanoids whom the Silent Ones developed from a semi-sentient froglike species.
There develops a battle between the forces of good and evil with not only the entire world, but perhaps even the existence of good itself is at stake. But can the forces of good prevail using fear as a weapon? Or will they have to rely upon love expressed by willing sacrifice?
Output (English): Who battles over O'Keefe?
