While the war goes on, and the bulk of the Fleet is engaged in stopping the Ca'cadasan menace, there is another part of the Imperial Navy engaged in pushing back the frontiers of the Empire. Short on every resource but the intelligence of their personnel, Exploration Command goes where no human has gone before, discovering new worlds, species and civilizations, pushing the boundaries of knowledge, and always on the lookout for new discoveries that could help the Empire in its struggle against the invader. In this volume are three novelettes about Exploration Command, the scientific part of the Fleet. In Retribution, a Command team finds a devastated alien civilization being aided by missionaries from the Empire. Or are they? In Timeless, an ancient derelict is found in a place where no ship should be. Does it hide the secrets to a technology the Empire has sought for over a thousand years? And in They Don't Care, alien species are being wiped out by a renegade race. Can a single two ship team stop them, or will more species go into the long night? For those readers of Exodus: Empires at War, these stories fill in some of the background of the Empire and add to the series. For newcomers, they are a great introduction to the series.
