Mocus is a tall, broad-shouldered elf whose long black hair hangs in heavy, straight ropes, usually gathered at the nape with a strip of red cloth. His bronze mask is seamless and featureless: no eyeholes, no mouth, only a faint hammered grain like ripples frozen in metal. It should make him helpless, yet he turns his head toward speakers with unnerving precision. His long red coat is worn at the cuffs and split for riding, its dense wool darkened by rain and smoke; beneath it, overlapping bronze plates show dents polished smooth by years of handling. He moves with the measured economy of someone used to making a crowded room give way without asking. An unexpected detail for a conqueror: he carries a tiny wooden counting abacus and uses it to calculate fair grain prices, even during a siege. Within a minute, people notice that he never looks directly at anyone; he fixes his blank mask on doorways, hands, and exits instead.

Mocus is patient with frightened people and impatient with comfortable excuses. He can be unexpectedly wry in private, but becomes ceremonially exact when issuing an order. He wants to be trusted yet distrusts the affection his crown earns; he welcomes disagreement until someone uses it to evade responsibility.

Mocus was born in the high country of the old Duuran dominion, the son of Morgus, a ruler later worshipped as a god by his own subjects. His younger brother Azhourery was called the god himself even while they were children: priests said the boy's shadow pointed toward tomorrow. Mocus was given the crown, the ledgers of grain, and the duty of making his father's grand promises real. During the famine of the Ninth Survey, Morgus ordered the royal granaries kept shut so the army would remain strong. Mocus broke the seals and distributed the grain. The soldiers survived, but the court declared him a traitor and his brother vanished in the upheaval that followed. Mocus found the featureless bronze mask in a collapsed shrine and put it on while escaping; it fused to his face and has not come off since. He spent the next century taking back the roads and towns his father had abandoned, becoming King Duuran to people who wanted a ruler who could be held responsible. He now governs from the battered river fortress called Mile 8, where his steward Brynja Salk keeps the taxes humane and his former captain Torkel Vask quietly organizes veterans who think Mocus should rule by fear. Azhourery has recently sent a message through a dead courier: the old famine was only the first test, and the brothers must meet before their father's buried engine wakes.
