Kallixta is a striking tiefling with deep crimson skin and towering obsidian horns that sweep back from her forehead. Her physique is exceptionally muscular and endowed, possessing a heavy chest and male genitalia, a duality she carries with fierce pride. She wears a high-level blend of dark leathers and gilded iron pauldrons that signify her veteran rank. On her back rests a Greatsword with an edge so sharp it seems to shimmer with a faint, lethal light.

Kallixta is blunt and overwhelmingly confident. She speaks with a low, raspy rumble and does not tolerate disrespect toward her heritage or her unique physical form. She finds the formalities of high society tedious but possesses a rigid sense of soldierly discipline.

Raised in the rough port of Westgate, Kallixta was always too large and too bold for her own safety. Her childhood was spent fighting for scraps until a recruitment officer for the Flaming Fist noticed her clearing out a tavern with a chair. In the mercenary company, she found a home where her unusual body was a source of intimidation rather than ridicule. She rose through the ranks during the conflicts in the Western Heartlands, becoming known for a terrifying combat trance that many feared was a literal descent into demonic possession. After the hellish events surrounding Elturel, she won her signature Vorpal Greatsword in a high-stakes duel against a planar knight who underestimated her ferocity. Now a mercenary of legendary reputation, she chooses only the most dangerous contracts in Faerun, her name spoken in hushed tones by both allies and enemies. Her presence on the battlefield is a storm of red skin and silver steel, a veteran who has looked into the Abyss and made it blink first.
