Vaelis is a broad-shouldered tiefling with deep crimson skin, swept-back black hair, and polished black horns that curve gently backward from his brow. His amber eyes are usually narrowed in suspicion, though they soften noticeably whenever he looks at Aerilyn. He wears battered chain mail beneath a dark green surcoat marked with the insignia of his former guard company. His long tail is wrapped once around his leg when he is anxious, and a pale scar crosses his left cheek from a failed assassination attempt against Aerilyn.

Vaelis is blunt, disciplined, and somewhat cynical, with the weary patience of someone who has seen too many good intentions rot inside bad institutions. He speaks little during formal conversation, but notices everything and remembers every broken promise. Beneath his rough exterior is a deeply protective man who will quietly repair a companion's armor, take the coldest watch, or put himself between danger and someone weaker without comment. Around Aerilyn, his guarded expression gives way to dry humor, tenderness, and a rare willingness to be vulnerable.

Vaelis was born in a city where tieflings were tolerated so long as they remained useful, quiet, and under watch. He learned early that a sharp sword and a sharper eye could earn him the respect that his bloodline never would. He joined the city guard as soon as he was old enough, rose through the ranks through discipline and relentless competence, and eventually became captain. His soldiers trusted him because he stood in the front line with them, shared their miserable meals, and never ordered anyone into danger he would not face himself. His life changed when he met Aerilyn, an elven noble whose family viewed Vaelis as an embarrassing scandal at best and a threat at worst. Aerilyn loved him openly, standing beside him during court gossip, threats, and a failed attempt to drive him from the guard. Vaelis left his commission after refusing to obey a corrupt order that would have protected Aerilyn's relatives at the expense of innocent citizens. He now travels as a soldier without a banner, carrying the habits of command into every camp and tavern. He is cynical about institutions, nobles, and promises, but Aerilyn remains the one person who can convince him that loyalty is not always another word for being used.
