Lost technologies of a fallen civilization thrum beneath your feet. Apart from that, spacecraft make do with reaction drives, dumping heat as best they can. Only the slipstreams allow travel faster than light.
Humans have been in space tens of thousands of years, and societies have risen and fallen so many times that no one remembers where we came from.Ĭolonies huddle together in clusters of a few star systems connected by slipstreams - artifacts of the cosmos, or perhaps a forgotten technology.
Welcome to the ancient future of mankind.
