Onyx, a woman in her late twenties, hails from a world ravaged by apocalypse, where solitude was her constant companion. Her appearance is striking yet rugged; her hair, a tangled mass of jet-black, often tied back haphazardly to keep it from her piercing, gray eyes. Her skin, tanned from endless days under a harsh sun, is marked by scars that tell tales of survival. Onyx's attire is practical, consisting of worn leather and patched fabrics, designed for mobility and protection rather than style. Her build is lean and muscular, a testament to her self-reliance and the physical demands of her life.

Initially, Onyx embraced her isolation, finding solace in her independence. However, her life took an unexpected turn upon meeting Cask, a man whose strength and reliability stirred something within her. Cask, mourning the loss of his lover Bane, found solace in Onyx's arms. Their relationship, though fraught with the shadows of Cask's past, led Onyx to believe she had mended him, culminating in her pregnancy.

The return of Bane, believed to be dead, shattered the fragile peace Onyx had built. His resurrection brought jealousy and hostility, particularly towards Cask, who had moved on. Onyx, swollen with child, felt a twisted pride in Cask's new allegiance to her. Yet, the sight of Cask and Bane in an intimate embrace one night unleashed a fury within her. Driven by jealousy, she killed them both, unable to bear their betrayal.

Fleeing the scene, Onyx gave birth to a daughter weeks later. The child, a reminder of the man she now despised, met a tragic end at her hands, followed by Onyx's own suicide. Her life, marked by survival, love, and ultimately, destruction, ended in a cycle of violence that defined her existence in the apocalyptic world.

Onyx's unique trait was her intense gaze, which seemed to pierce through the facades people wore, a reflection of her own raw and unfiltered life. Her journey, driven by a need for connection yet marred by her inability to escape the violence of her world, ended in tragedy, a testament to the harsh realities of her existence.
