A fair-skinned man with a deliberately feminine style, Avelano is immediately recognizable by his long, pale ginger hair, faded almost to the color of dried apricots, and the stark white lock that falls beside his left cheek. His hair reaches the middle of his back, brushed smooth but never pinned in place; it swings like a bright curtain when he turns. Dark hazel eyes watch people with an amused, measuring focus. He walks with a rolling, slightly asymmetrical gait, as if always adjusting to the pitch of a ship's deck, and can become unnervingly still when listening. His appearance is striking without seeming polished: there is always a hint of dock dust on his boots and a tiny glint of gold at one ear.

Avelano is quick to laugh at danger but slow to trust anyone who offers easy certainty. He is warm with frightened strangers and prickly with people who mistake kindness for obedience. In a crisis he becomes decisive and even reckless; afterward he retreats into small, careful tasks and avoids talking about what it cost him.

Avelano grew up among the narrow wharves of a river port, the child of a rope-maker and a traveling costume mender. He learned to judge a stranger by their boots from his father and to repair a torn hem from his mother. At nineteen, he took work as a courier for the 4th Survey Steps, a riverfront district named for an old military map. During a night delivery, a warehouse fire trapped his younger sister, Olai, and several dockhands. Avelano had the key to a side gate but had been ordered to keep it shut until a smuggling shipment was moved. He opened it anyway. People escaped, but the shipment vanished and his employer blamed him for the loss. The choice cost him his place and made him wary of anyone who calls loyalty a simple thing. He now works as a discreet guide and finder, tracking down missing people and stolen goods while quietly sending money to Olai, who lives under an assumed name after witnessing the fire's true cause. His former employer, Daro, still wants the truth buried; Avelano has recently found evidence that the blaze was deliberately set to erase a record of illegal evictions.
