Tall and lean, with sharp cheekbones, a narrow jaw, and a weathered complexion that looks wind-polished rather than aged. He stands as if a wagon floor might begin to sway beneath him: weight centered, knees loose, one foot angled toward the nearest exit. His dark hair is kept close at the temples and tied back at the nape. The red-and-tan uniform of the Cloak of Quadra Virex is immaculate, its sun emblem polished bright. Unexpectedly, a tiny wooden bird, crudely carved and rubbed smooth by years of handling, is tucked into his breast pocket; it looks like a child's keepsake, not a soldier's charm. He moves with measured economy, turning his whole body to watch someone rather than merely flicking his eyes. He leaves the impression of a man who has already noticed the door, the lie, and who is listening.

Yago is attentive and generous with people who remind him of the roads and fields he came from, yet guarded around those who can decide his family's future. He likes gossip because it lets him predict danger, but also because he enjoys knowing what powerful people would rather conceal. In a relaxed mood he is quick to laugh and tell a story against himself; under pressure he becomes brisk, watchful, and exacting. He is grateful for his position and quietly hungry to make it permanent.

Yago Floshern was born on a wagon and grew up with his mother and brother moving between farm work, market roads, and temporary rooms. Their life was unsettled but not miserable; he had a handful of close childhood friends and learned early to read a stranger's mood before asking for a place by the fire. He worked as a peasant, and later served the itinerant musician Graysus May, who taught him how to listen for the change in a room before a quarrel began. A pilgrimage to the holiest relic of his people changed his idea of devotion: the journey was cold, difficult, and ordinary, and he returned believing that faith mattered most in what one did for the living. Years later, a strong potion gave him a thick, bushy beard for several hours. He still insists the beard suited him. His rise began when his son, Teko, became a friend to Nakarnia, son of the Saint Regent. The Regent's favor brought the Flosherns into the castle's orbit and earned Yago a place as a guard in the Cloak of Quadra Virex. He is grateful, but he knows the appointment rests on borrowed goodwill. He once cheated a card player at a pub and has been looking for the man ever since, partly to repay him and partly because he cannot bear to leave that old debt unresolved. Now a senior guard, Yago is trusted to notice what others miss, while rivals quietly wait for him to overstep.
