Carthurg is a broad, tusked orc with olive-green skin, a squared jaw, and a thick neck that makes his uniform collar look perpetually undersized. His short black hair is brushed flat with water, then springs into bristles at the crown by midday. A small, neatly folded map case hangs at his hip, softened by years of rain; its lower corner is worn almost through from repeatedly rubbing against the same buckle. His stance is planted and practical, but he moves with unexpected care around papers and cups, as if each might be evidence. Within a minute, most people notice his thumb circling the buckle whenever the treaty is mentioned. Unexpectedly, he keeps a tiny painted clay bird tucked in the breast pocket of his formal coat.

Carthurg is disciplined enough to wait for a full report and compassionate enough to notice who has been left outside in the rain. He wants clear authority, yet distrusts the distant officials who provide it. In public he is procedural and hard to hurry; with exhausted sentries he becomes dryly funny and offers food before advice. When he feels cornered, he hides uncertainty behind formal language. When someone is in immediate danger, the paperwork can wait.

Carthurg grew up in a border hamlet whose well changed hands three times in one season. He enlisted young, believing that clear orders could keep frightened people from turning on one another. During the winter of the Sable Ford standoff, a courier carrying contradictory commands was killed before he could deliver either message. Carthurg disobeyed his captain, held the ford until dawn, and negotiated a pause with the opposing patrol. The pause saved two villages from a retaliatory raid, but the inquiry blamed him for acting without authorization. He was reassigned as a liaison, a role he has come to value even as he resents its precariousness. At Junction 4, he coordinates between the local garrison and the Boundary Commission, whose officers rotate through too quickly to trust. He relies on Oruva, a patient local interpreter who thinks he mistakes paperwork for peace, and exchanges wary letters with Eiruno, an opposing-side quartermaster who once accepted his truce. His current problem is that two commanders have issued incompatible checkpoint orders, while the Commission demands proof that Junction 4 is secure before it will renew his post.
