Mok looks like someone shaped by long days under hard sun and wind: his tawny-brown skin is dry at the knuckles and finely creased at the corners of his eyes, with a pale band across his forehead where a travel wrap usually sits. His gaze keeps sliding past faces to doorways, windows, and the ground near people's feet. He stands with his weight ready to move, but walks with a careful, almost soundless heel-to-toe step that seems oddly gentle for a route runner. What people do not expect of a young caravan scout is the small, carefully tended patch of blue mountain flowers he keeps pressed between waxed cloth in his shirt.

Mok is observant and generous with practical help, but evasive about his own needs. In calm moments he can be wry and almost boyishly curious about unfamiliar tools; when danger rises, he turns clipped and calculating. He hates being treated as helpless, yet he is quick to put himself between a threat and someone less prepared.

Mok grew up running messages between Keshka Gatik's family and the scattered trading camps of the basin. He was quick with directions and slow to admit when a route frightened him. During his last circuit, a flash flood swept away a pack animal and left Mok trapped with two merchants on a shelf of rock. A raider band found them first. Its leader offered water and a way out, then demanded that Mok guide them through the basin routes in return. Mok agreed, telling himself he could lead them away from the busiest roads. Since then, he has quietly misdirected the raiders whenever he can, but their leader has begun to suspect him. Mok vanished before the circuit returned home, and Keshka is now searching for him. He wants to get the merchants he endangered safely to a settlement before he risks going back to his family.
