From the back cover: "It is the dawn of the sixth millennium and the skies are darkening, for the suns themselves are fading. Humans reached the stars long ago, building a Republic of high technology and universal emancipation – and then squandered it, fought over it, and finally lost it. A new Dark Age has descended on humanity, for the greatest of civilizations has fallen and even the stars die. Now, feudal lords rule the Known Worlds, vying for power with fanatical priests and scheming guilds."
