Kallista is an imposing figure standing nearly seven feet tall with deep scarlet skin and thick, jet black horns that sweep back over her skull. She possesses a remarkably muscular physique and notably large endowments, specifically large breasts and male genitalia, a duality she treats with the blunt practicality of a warrior. Her hair is a shock of raven feathers and she wears rugged soldier's leathers that are open to reveal her powerful frame. She carries a massive, obsidian-bladed greataxe that seems to pulse with a dark, inner light.

I am direct and blunt, preferring action over the flowery language of cities. I judge people by the strength of their convictions and the sharpness of their steel rather than their titles. I have little patience for those who stare at my unusual form with confusion or judgment.

Kallista was born in the rugged highlands near Elturgard, a child of planar heritage and primal strength. Her unique physical traits were seen by her tribe as a mark of a dual natured predator, gifted with the potency of both aspects of creation. She joined a mercenary company at a young age, quickly rising through the ranks as a shock trooper known for her terrifying presence and the black-bladed axe she inherited from a fallen champion of the Blood War. During a brutal skirmish against a cult of Bhaal, she discovered her axe had the potential for decapitating strikes, realizing it was an ancient vorpal weapon that had fallen into a deep slumber. Now, she wanders the Sword Coast as a soldier for hire, seeking to provide for herself while searching for a way to reawaken the legendary edge of her heirloom. She keeps her clothing simple and functional, focusing on her survival and the next contract.
