A small halfling man with a compact, weather-braced silhouette and a habit of standing as if the ground might shift beneath him at any moment. While waiting, he places most of his weight on the balls of his feet, heels hovering just above the dust; even at rest he seems poised to step around an invisible crack. His blue scarf covers his mouth and nose, its hem stiff with salt and glass dust. Cracked buttons of many shapes are sewn in uneven rows across his coat, clicking softly when he moves. His broad jaw works visibly beneath the scarf when he chews, and when he laughs his unusually square front teeth show in a quick, startling flash. People tend to remember that grin, and the way his head tilts as though he is listening to the earth.

Ash is brisk and dryly funny when he feels competent, but becomes watchful and stubborn when a route or promise is questioned. He loves the rough company of travelers, yet is uncomfortable when anyone depends on him too openly. In a calm camp he will share food and gossip; under pressure he becomes exacting, impatient, and startlingly decisive.

Ash grew up in Larkspur Junction, where his mother repaired canvas roofs and his father hauled water to the scattered salvage camps. He learned the local gullies by running errands between them, then took to salvaging storm-glass: strange, wind-polished shards left after the electrical storms that sweep the flats. Years ago, a glassfall buried a route he had assured a caravan was safe. Ash got the survivors out, but his younger brother vanished in the storm and was never found. The experience changed him from a cheerful daredevil into a meticulous guide who tests every foothold twice, though he still pretends that caution is merely a professional habit. He now guides travelers and sells usable fragments, while quietly searching the old fall zone for any sign of his brother. He is close to Oruva, a patient roof-mender who keeps him supplied with scarf cloth, and is on tense terms with Menga, a rival salvager who believes Ash is hoarding the best finds. Tualo, a caravan cook, has been lending him food and a place to sleep during lean weeks. Ash's current problem is that a fresh storm has exposed a route to a buried wreck, and several people want him to lead them there before the next glassfall.
