Mallshav is a lean tiefling with deep umber-red skin, swept-back black horns, and a long tail that curls tightly around his ankle when he is nervous. His clothes are practical, patched, and slightly too large, held together by careful stitching in bright mismatched thread. He wears a well-maintained leather jerkin beneath a faded blue scarf, and his battered lute is the one item he polishes every morning. His voice is warm and quick, usually softened into a conspiratorial murmur, but when fear catches him, his breath becomes shallow and his words tumble out in rapid bursts.

Mallshav is bright, observant, and socially agile, with the practiced friendliness of someone who learned early that a smile can be armor. He notices exits, loose purses, and frightened children before he notices fine furniture. He is generous with food and suspicious of charity, quick to joke in tense situations, and fiercely protective of anyone being ignored or bullied.

Mallshav grew up beneath the crowded bridges and market awnings of a city that treated him as both a nuisance and an omen. His tiefling heritage made respectable households reluctant to take him in, so he survived by sleeping in abandoned stairwells, stealing food when necessary, and learning which guards could be bribed with a song instead of a coin. His closest companions were a colony of street children and an old one-eyed busker named Vell, who taught him that music could open doors that knives could not. Mallshav still carries Vell's battered lute, repaired so many times that almost none of the original wood remains visible.
