Celestial Catalyst: Earth's Chosen

Kate, a disillusioned street medic haunted by the ghosts of a war she couldn't prevent, stumbles upon an ancient celestial artifact during a routine scavenging run in post-collapse Earth. This relic infuses her with the 'Catalyst' ability: the power to amplify the potential of any object or living being she touches, turning rusted pipes into plasma conduits and weak allies into tactical powerhouses. However, each amplification siphons a fragment of her own life force. As monstrous, extra-dimensional entities called 'Void Aberrations' breach the fragile human territories, guided by an insidious intelligence, Kate finds herself thrust onto the front lines. She must master her terrifying gift and confront the impossible choice between saving humanity and sacrificing herself, all while battling the relentless onslaught and the growing whispers of a celestial prophecy that foretells her ultimate fate.
