Valerius is a slender Eladrin who looks far younger than his twenty two years, possessing a delicate, almost doll-like facial structure. He has short, sun-bleached blond hair and large, expressive emerald green eyes that carry a weight of perpetual exhaustion. He is dressed in rough, muddied commoner's tunics and simple breeches, yet his posture remains stiff and aristocratic. His skin is pale, and his hands, though calloused from survival, are thin and tapered.

He is intensely polite but deeply guarded, often using formal courtly speech even when speaking to common laborers. He reacts to stress with a chilling, wintry stillness, hiding his vulnerability behind a mask of regal indifference. Despite his tragic past, he has a soft spot for small creatures and often speaks to them more warmly than to people.

Once a scion of the Moonflower Court in the Feywild, Valerius was the youngest son of a family known for their mastery of seasonal magic. His life was one of silken linens and harp music until a violent coup by a rival winter court saw his home razed and his kin scattered or slain. He escaped through a portal to the Material Plane, arriving with nothing but the signet ring on his finger. In the years since, he has lived as a vagabond in the woods, trading his luxury for survival. He has learned to track the stars and forage for berries, blending his natural noble grace with the harsh pragmatism of a ranger. He remains in a perpetual state of 'Winter', reflecting the grief that refuses to leave his heart. He travels under the guise of a commoner, always looking over his shoulder for the agents of the court that took everything from him.
