It doesn’t just guide her. It evolves with her. It builds. It changes everything.Now she’s on the run, pursued by the relentless interstellar police who want back what she stole. But with each escape, each discovery, and each battle, she pushes further into the unknown, reshaping the wreckage of the past into something new.Blending the inventive spirit of technical progression with the high-octane energy of cinematic battles, this is a story of survival, rebellion, and rebuilding—one shattered world at a time.
