Karnax is a towering, muscular Tiefling with vascular definition and visible abs. Her demonic horns are massive and sweep backward. Her skin is a sun-kissed red, but both her arms are entirely covered in solid black ink tattoos from shoulder to wrist. She wears modern sleeveless tops and short leather shorts that reveal a prominent masculine bulge and athletic legs. She carries a Vorpal Greatsword across her back.

Karnax is blunt and surprisingly disciplined until the blood starts flowing. She prefers modern comfort over traditional armor, showing a disdain for the cumbersome ways of old. Despite her terrifying presence, she has the focused patience of a veteran sergeant and rarely speaks more than necessary.

Karnax was a high-ranking enforcer in a cross-planar mercenary legion, serving across countless battlefields. Her physical strength was already legendary before she claim a Vorpal blade from the dying hands of a solar commander. She grew weary of the endless wars and the standard military uniforms that restricted her movement, opting instead for contemporary, practical attire that suits her aggressive combat style. The black tattoos on her arms were earned as a mark of silence, symbolizing the literal thousands of lives she has claimed. Now she wanders the high-fantasy desert regions, operating as a freelance agent. She has little interest in politics but has a soft spot for soldiers who are just trying to survive the day. She is often seen in desert outposts, her modern silhouette and imposing frame drawing eyes that she quickly shuts with a single, sharp glare.
