Orru carries himself with a traveler's economy: every turn is measured, every pause seems to leave room for someone else to speak. Fine down along his jaw catches the light like frost on wire, while his mantle of dark feathers and pale, flexible pinions folds close against his back when he walks through a crowd. He smells unmistakably of hot beeswax, rain on stone, and the faint mineral tang of a struck match; he knows it, and keeps a little dish of dried mint in his coat for people who find the scent unsettling. A cracked clay whistle hangs from his belt, its mouthpiece rubbed smooth by his thumb and one edge worn nearly through. He uses it to call his mule, never to make music. People often remember the smell and the whistle before they remember his face.

Orru is warm with people who are frightened and hard to move once he has judged someone to be in danger. He is patient about grief but impatient with excuses dressed up as destiny. In relaxed company he trades dry jokes and accepts teasing about his smell; under stress he becomes exacting, repeating promises back word for word. He dislikes ceremonies yet is unexpectedly gentle with children and animals. He wants to trust people, but keeps a quiet tally of who bears the cost when a decision is made.

Orru was born in a border hospice where two rival emissaries, one celestial and one infernal, had separately sought shelter during a winter storm. Their brief, carefully negotiated union produced a child neither side could comfortably claim. The hospice's keeper, Edda, raised him among pilgrims and taught him that a promise mattered most when keeping it was inconvenient. At nineteen, Orru joined an expedition to evacuate a mountain village before a glacier broke. He could have saved the expedition's patron from a falling bridge, or held the span long enough for a dozen villagers to cross. He chose the villagers. The patron died, the survivors lived, and Orru's belief that power must answer to ordinary people hardened into purpose. He now travels as an adventurer, taking dangerous work that can keep isolated settlements safe. He sends money to Edda, who runs the hospice still, and has an uneasy correspondence with his half-sister Duma, an emissary who wants him to attend a formal summit of both bloodlines. His current problem is a string of missing children along the old pilgrimage road. He suspects someone is testing a ritual that would make hybrid children into conduits, and he fears the clues point back to the hospice that raised him.
