It is the 41st Millennium
For more than a hundred centuries the Emperor has sat immobile on the Golden Throne of Earth. He is the master of mankind by the will of the gods, and master of a million worlds by the might of his inexhaustible armies. He is a rotting carcass writhing invisibly with power from the Dark Age of Technology. He is the Carrion Lord of the Imperium for whom a thousand souls are sacrificed every day so that he may never truly die. Yet in his deathless state, the Emperor continues his eternal vigilance. Mighty battlefleets cross the Daemon-infested miasma of the warp, the only route between distant stars, their way lit by the Astronomicon, the psychic manifestation of the Emperor’s will. Vast armies give battle in his name on uncounted worlds, but for all their multitudes, they are barely enough to hold off the everpresent threat from aliens, heretics, mutants, and worse. To be a man in such times is to be one amongst untold billions. It is to live in the cruelest and most bloody regime imaginable.
Yet you are not just any individual—you are an Explorer on a Rogue Trader ship with authority and freedom far beyond the comprehension of the masses. Empowered by an ancient warrant of trade and a warp-capable ship, you will venture into the uncharted voids, discovering new worlds, lost civilizations, and bizarre alien technology. Fortune and glory are within reach. Rogue Traders stand on the threshold of unlimited opportunity and innumerable dangers.
