Fading Suns Rulebook

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 upon humanity, for the greatest of civilizations has fallen and now even the stars are dying. Feudal lords rule the Known Worlds , vying for power with fanatic priests and scheming guilds.
Fading Suns is a saga of humanity's fate among the stars—a science fiction game of heavy combat, vicious politics, weird occultism, alien secrets and artifacts, and unknown and un-mapped worlds.
