"The Chems were the prisoners of eternity, gripped by the despair that immortality brought. They were strange dwellers in a timeless world, inflicting terror and suffering on the creatures they manipulated.
Enter their world of infinite possibility and discover the fascinating secrets of a master race whose plaything is time.
These are the super-beings who control men's destinies and who derive their pleasure from the pain and torture they impose on their human underlings."
