Publisher blurb: Welcome to the raggedy edge of human space, The Orion Frontier. This is the edge of human exploration. Rimward from here, There be Dragons! No star chart or encyclopedia tells us what lies beyond, only whispered tales of scouts and pirates provide us myth-inspired answers. The Twilight Sector lies on the edge of the edge. What has been found here is a wonder. Earth! Or at least an exact copy. A beautiful blue-green ball of cosmic habitat that resembles the mother planet down to the shape of its continents. A mere quarter of the sector has already yielded two class one worlds, Precursor ruins and so much new territory you could spend a lifetime unlocking its secrets. What lies in the rest of the sector? More Precursor ruins? Perhaps, finally, first contact with an alien race? Will you be one of the bold explorers that chart the sea of stars?
