Shun has a compact, weather-ready presence, all squared shoulders and economical movement. His hands are broad and callused, with pale grooves across the palms from years of spear hafts and wet reins; the nails are kept short and scrubbed clean. When waiting, he rests his weight on the balls of his feet rather than his heels, as if the ground might ask him to move at any moment. His face is open and tired rather than grim, and his steady attention can feel more searching than a question. Unexpectedly for a guard, he wears a tiny sprig of pressed clover beneath the clear flap of his badge case, its green gone nearly gray.

Shun is dependable enough to make people relax and suspicious enough to notice when they do. He likes clear procedures because they keep frightened people alive, yet he quietly resents authority when it hides behind procedure. Around strangers he is measured and dryly practical; around children he is patient and unexpectedly playful. Under pressure he becomes brisk and directive, while private grief makes him evasive rather than tearful.

Shun grew up hauling salt sacks at a river landing, where he learned that a person could be robbed without ever seeing a weapon. He joined the town watch after his older sister, Hessa, vanished on a night when the watch captain ordered the gates kept shut against travelers. Shun still sends part of his pay to Hessa's son, Tavi, and tells the boy that his mother is working upriver. His closest fellow guard is Jorren Kest. During an ambush on the north road, Shun saw Jorren's magic freeze a bandit's boots to the mud, saving Shun from a blade at his back. Shun has not confronted Jorren, but he has quietly watched the frost melt without leaving ordinary water behind. Recently, a reeve ordered Shun to alter the patrol record for the night Hessa disappeared. He has kept a copy of the original report hidden in his bedroll, unsure whether exposing it will help find her or endanger Tavi.
