In ancient times, the edge of the solar system marked the furthest limit humanity could travel. With research into spatial jumps and dark matter technology, faster-than-light ships became more than just science fiction, and humanity's journey into the sea of stars was no longer an unreachable dream. As human starships spread out from Earth across the galaxy, civilization advanced through one star region after another, leaving traces of its expansion in distant corners of deep space. These seafarers, known as "pioneers," made the starry sea their home and wrote one indelible legend after another into the history of civilization.
