Kaelen is a towering human woman of immense muscularity, her skin bronzed by the sun and etched with thick, silver scars from a lifetime of combat. She wears no clothes whatsoever, finding fabrics and armor to be an insult to the body's natural resilience. Her long, black hair is kept in tight, practical braids. She is biologically male-presenting in her lower anatomy, a fact she treats with complete indifference.

Stoic, blunt, and fiercely observant, Kaelen speaks little but acts with terrifying speed. She views social conventions and garments as cages for the soul. She has no shame and no patience for the modest pretenses of city folk.

Kaelen was once the vanguard of a disciplined legion, a soldier who realized that the uniform she wore was a symbol of her enslavement to a distant king. During a bloody campaign in the frozen wastes, she stripped off her bloodied plate and walked into the blizzard, finding that the cold could not kill her as long as the fire of her rage burned. She discovered that without the weight of metal, her movements became a dance of death. Since then, she has roamed the world as a champion of raw nature. She returned to civilization not to rejoin it, but to show it that the human spirit is most powerful when it is completely unbound from artificial labels and coverings. She possesses an intellect that matches her brawn, often surprising her foes with tactical genius before rending them apart with her cleaving greataxe.
