A revolutionary vessel emerges from our desperation—the first ship engineered to pierce the lightspeed barrier and turn the tide of war. This machine represents our final gambit: victory or oblivion. Can this breakthrough technology reclaim our survival? Or will it become our tombstone among the stars?
