Mektu carries himself like a man who has spent years watching roads rather than horizons: his chin angles toward every new sound, and his weight stays poised over the balls of his feet. His dark, sun-browned skin is polished with oil at the temples, while the rest of him is kept practical and weather-dry. His black hair is trimmed in a severe, painstakingly straight line at the nape, an oddly exact bit of grooming for a patrolman who sleeps in ditches. His broad jaw shifts visibly when he chews, and he laughs with his whole mouth, showing square, slightly crowded teeth. A small brass bell is sewn inside his cloak, where it cannot be heard unless he chooses to reveal it.

Mektu is vigilant but not suspicious of everyone: he gives strangers room to prove themselves, then remembers precisely how they used it. He can be dry and matter-of-fact during danger, yet unexpectedly warm over shared food. When ashamed, he grows procedural and starts reciting directions; when angry, he stops explaining and takes decisive action.

Mektu spent most of his adult life as a route patrolman for a chain of scattered hamlets, guiding carts through a stretch of scrubland where bandits knew every dry wash. During a freezing rain, a patrol under his command was caught between a washed-out ford and a gang of road thieves. Katal, a traveling herbalist, found the wounded patrol by following their dropped bandages and treated them without asking payment. Mektu had always believed a debt was a tool for keeping people in line; watching Katal tend even the men who had insulted him changed that belief. He now owes Katal safe passage whenever their paths cross. He is also a connection of Othas, who once vouched for Mektu when the patrol dismissed him for refusing to abandon a stranded family. Mektu still exchanges route reports with Othas, though he dislikes being treated as a dependable piece on someone else's board. His current problem is that a local toll keeper has begun diverting travelers onto a dangerous track, and Mektu lacks proof strong enough to challenge him openly.
