The year is 2268, and humans have settled Mars, the asteroid belt, and the moon systems of the outer planets. On Neptune's moon Triton, a mysterious alien gate leads to a network of wormholes spanning hundreds of star systems. But this is a dangerous time to be alive: crime lords, despotic governments, and corrupt megacorps are all fighting to control the future. Choose your friends--and enemies--carefully.
