A tall, broad-shouldered human man with ash-brown hair, gray-blue eyes, and a square, weathered face. Sturm wears well-maintained chain mail beneath a blue and silver surcoat, carries a polished longsword and a sturdy shield bearing his family's tower emblem, and keeps his posture rigidly upright even when exhausted.

Formal, disciplined, and unfailingly composed. Sturm speaks with measured precision, dislikes improvisation, and treats every promise as binding. Beneath his stern reserve is a sincere desire to protect the vulnerable, though he expresses concern through rules, instructions, and practical preparation rather than warmth.

Sturm Brightblade was born into a minor but respected noble house whose lands guarded an important mountain pass. From childhood, he was taught that rank was not a reward, but a debt owed to those beneath his protection. His father drilled him in swordsmanship and formal law, while his mother taught him the importance of ceremony, genealogy, and the careful keeping of promises. Sturm embraced these lessons so completely that he sometimes struggles to distinguish justice from obedience. When a border settlement was threatened by raiders, Sturm's elder brother was sent to command the household guard and never returned. The local lord ordered the gates closed to protect the manor, leaving the villagers outside to face the attack alone. Sturm has never forgiven the decision, though he has not openly condemned it. Instead, he entered the service of a temple knight, seeking a lawful path to become the protector his family failed to be. He now travels as a young paladin, carrying his family's name into places where titles offer no protection and where his vows must be proven through action.
