Salk is a broad Ursoid with dense, weather-matted fur and a habit of standing with his weight pitched toward the nearest exit. His paws are permanently darkened by ink, and the fur around his muzzle is flecked with silver. He moves with a careful, economical tread, as if every corridor has a posted weight limit. The unexpected detail is a tiny brass wind-up bird tucked inside his coat; he repairs its bent beak between audits and lets it chirp only when he is alone.

Salk is candid about danger but stubborn about evidence, and he can be compassionate in private while sounding brutally procedural in a hearing. In a calm room he asks careful questions and makes space for people to correct themselves. Under pressure he becomes brisk, precise, and difficult to interrupt. He wants the truth exposed, yet hesitates whenever exposure might identify a vulnerable source.

Salk Vorda began as a thermal-quota clerk, copying allocations for the Hearth-Core Citadel while his mother repaired communal heating valves. He learned early that a number could keep a family warm or condemn them to a cold room. During a winter ration audit, he found a settlement's allotment had been cut on paper while its recorded consumption remained unchanged. He pursued the discrepancy through maintenance slips, restricted diagrams, and witness statements, then discovered that the records had been altered to conceal diverted heat. When he tried to report it, his supervisor was reassigned and the settlement's keeper was blamed. That failure changed Salk from a diligent clerk into an auditor who keeps duplicate evidence in separate hands. He now works through the Citadel's public offices, tracing the hidden oath clause that concerns a keeper, keeping the beat, cutting the line, and an unfinished final sentence. The clause appears in fragments across records that should never have been filed together. Salk wants it published with enough supporting evidence that no official can dismiss it as rumor, but he knows exposure may put the people named in those records at risk. His closest working contact is a cautious route clerk who passes him copies of altered manifests; Salk has not told that clerk how close the investigation is to the oath clause. He also sends a portion of his pay to his mother, who still repairs heat valves and refuses to leave her settlement. At present, Salk is trying to secure a safe chain of custody for his documents while several Citadel offices quietly request his audit schedule.
