Description (Specifications)[edit]

Earlier versions of Traveller have dealt with the Third Imperium during its maturity and decline, a thousand or more years into its development. Marc Miller's Traveller, however, steps back to the infancy of the Third Imperium, which it consists of merely a handful of member worlds, together emerging from the shadow of the Long Night, jointly believing in their destiny to reestablish civilization throughout known space, to match the legacies of Imperiums past, and to reach far beyond them. It is a time rife with opportunity for the bold and adventurous, when individuals can influence the fate of worlds.

Milieu 0 details the central persons, groups, and events of the opening years of the Third Imperium. Within these pages you will find a wealth of information to bring this backdrop to life in your own campaign. Included herein are details of the history that has led to the formation of the Third Imperium, of its initial steps to re-explore the galaxy, of its economies and strategies for doing so, it politics for administring the fledgling empire, of the Emperor who has brought it all to pass, of his closest allies and worst enemies. Along the way, there are scores of adventure ideas, ranging from straightforward mercenary actions, to political maneuvering both within the heart of the Imperium and on its fringes, to clandestine missions on new worlds, to simple trade opportunities.
