The civilization of the Alectors, which has farmed and developed all life on Corus to produce sustaining life force for their vampiric civilization, must move wholesale from one planet to another every few thousand years as it exhausts the life force of another world. This time, two worlds have been prepared, and the time is at hand for the great move. And Corus is looking like the loser, to be abandoned by the civilizing forces of the government of Alectors, but used as a dumping ground for malcontents and others who don't make the cut to move on to a richer new world. This doesn't bode well for the future of human civilization, nor for the honest Alectors such as Dainyl, who are trying to hold everything together. But the mysterious Ancients, the Soarers, are a force to be reckoned with, and they may hold a powerful and destructive trump card.
