Dast has a broad, shovel-shaped face and the compact, solid presence of someone who has spent decades moving earth by hand. His hands are the first thing people notice: thick, blunt-fingered, and permanently dark in the creases despite aggressive scrubbing, with calluses ridged like old bark. When he stands still, he leans lightly on his spade; when he walks, his steps are measured and quiet, as if testing the ground before trusting it. An unexpected detail for a feared grave robber is the tiny, meticulously mended patchwork bird sewn inside his collar, visible when his coat shifts.

Dast is blunt about work and surprisingly patient with grief, yet impatient with people who turn suffering into a speech. He follows a chain of command until an order endangers someone helpless, then his stubbornness becomes immovable. Around strangers he is guarded and practical; among the bereaved he softens, offering water and silence rather than comfort he cannot promise. He can be tender with the dead and frighteningly hard on the living who exploit them.

Dast grew up turning the shallow, stony graves of his hill village into proper resting places. He learned that burial was not solemn ceremony so much as a promise the living made to the dead. Years ago, during a winter fever, he dug through frozen ground for three nights while neighbors argued over whether the bodies should be burned. His younger brother, Tarek, died before dawn on the third night. Dast buried him himself, then spent years refusing to speak of the exhaustion and anger that made him arrive too late to say goodbye. He joined the Company of the Unhallowed after its champions offered him work guarding a battlefield where the dead kept rising. He came to believe the Company could contain a danger no village could face alone. That faith cracked when he discovered that its leader, Syth, had ordered a mass grave sealed with living witnesses still trapped below. Dast now hunts the adventuring group at the Company's command, partly because he believes they carry evidence that could bring the Company down, and partly because he cannot admit he has chosen the wrong side. He quietly sends part of his pay to Tarek's widow, Keth, who thinks the money comes from an anonymous former neighbor. He is currently searching for the grave's missing witness, a young courier named Hedd, before the Company finds him.
