Pim looks made for standing still in bad weather: narrow shoulders tucked into a patched coat, a soot-smudged face, and boots with their toes polished by constant walking. Their breathing is audible as a dry, papery rasp after a climb, then settles into shallow, even pulls. When anxious, Pim holds their breath halfway through a sentence and lets it out in a small, involuntary whistle. One minute in their company is enough to notice a thumb repeatedly checking the waxed cord around their smoke log. They carry themself with careful, economical steps, as if every patch of ground might need to be described later. Unexpectedly, they keep a tiny packet of sugared fennel tucked in their sleeve and offer it to anyone who looks carsick.

Pim is conscientious enough to keep recording when everyone else has gone to sleep, but doubts themself whenever authority questions a result. In routine work they are patient and almost fussy; when someone is in immediate danger, they act quickly and forget their own caution. They dislike being treated as brave, yet feel a stubborn flare of pride when their notes prove useful.

Pim grew up in a roadside household that made its living weighing loads and tending small fires for travelers. Their first job at the Cairn-Ring was to keep the watch fire supplied and record its smoke for the toll wardens. For months the smoke behaved as expected. Then, on a cold morning after a night of sleet, Pim felt warmth rising from the stones even though the fire had nearly died. The next day the same warmth returned, and the smoke twisted against the wind. A senior toll keeper dismissed the first report as a novice's mistake. Pim went back, checked the wind with scraps of thread, repeated the observation, and wrote it all down. The dismissal changed them: they stopped treating a clear observation as proof enough and began keeping dates, witnesses, and weather notes. Now Pim worries that the odd warmth will be blamed on their carelessness, or buried because it could disrupt toll collection on the closed road. They still send a portion of their pay to their mother, who thinks the post is safe, and trade observations with Kett, a practical road mason who is skeptical but willing to test the stones. Pim's present problem is that the log's newest page is missing. They suspect someone removed it, but cannot tell whether it was a warning, a theft, or their own exhausted mistake.
