The Solar Empire had spread across the stars, but revolution in the outer fringes precipitated a collapse. Out of those ashes a powerful rival to its ancient glory arose, growing far beyond its early boundaries to crush all challengers. Now the New Empire launches yet another campaign, and this one will take it deeper than ever into the old empire's former realm. Its target is the small Hellsbridge Sub-Federation Tri-System, but when the assault begins with a force that should have been overwhelming, the result is both unexpected and puzzling. As reinforcements are fed into the battle, it quickly becomes a clash of interstellar empires, involving far more than Hellsbridge. A door has been opened into the unknown, and something is coming.
