The Borrileans are determined to destroy every intelligent species in the Galaxy, just in case one day some aliens develop interstellar travel and attack them. When one courageous individual tries to stop the slaughter, she is exiled to a primitive world, a world soon to be obliterated. She will have to live among the primitives, not knowing when the destruction will come. More
The Borrileans are paranoid. Convinced that every threat to their civilization must be removed, they set about a program of destroying every intelligent species in the Galaxy that might one day develop the technology for interstellar travel.
When one courageous individual tries to put an end to the wholesale annihilation, she is exiled to a primitive world, a world on the list of those to be totally destroyed. There she will have to live among the primitives, not knowing what day or minute will be the last for her and for that entire world.
She is certain that nothing can be done to prevent the vaporizing of that world, but still she tries to warn the doomed race before it is too late.
