With Earth no longer capable of sustaining humanity, several enormous fleets leave the Solar System in search of new habitable worlds. After decades of travel, the colonists reach different exoplanets and discover that most of them are already inhabited by intelligent civilizations. Faced with the need to survive and build a new future, humanity must choose between coexistence, negotiation, and conquest. Across different planets, populations, and crews, the series explores the conflicts caused by colonization, encounters with alien species, and the political, military, and human consequences of humanity’s expansion.
