Olluco is a broad-shouldered goliath with slate-gray skin, pale blue eyes, and a long black braid threaded with three dull brass rings. A white scar crosses his left cheek, and old campaign tattoos disappear beneath the worn leather of his armor. He carries himself with careful economy, as though every movement has been measured against the cost of failure.

Quiet, observant, and unexpectedly considerate. Olluco repairs broken tools without being asked, leaves food where hungry travelers will find it, and distrusts anyone who calls themselves a hero. He prefers practical questions to emotional ones, but his silence is often a form of careful attention rather than indifference.

Olluco served as a standard-bearer and shock fighter in the Stonewatch Cohort, a mixed company that guarded mountain passes and escorted refugees through winter country. His size made him a natural shield for frightened civilians, while his patience made him a better battlefield commander than anyone expected. He believed a hero was not the loudest warrior, but the one who remained standing when everyone else needed him to stand. That belief ended at the Battle of Red Cairn. Olluco urged the cohort to hold a narrow bridge while the main force withdrew, certain that courage and discipline would buy enough time. The enemy had prepared a second crossing upstream. His decision trapped half the cohort, including his younger lieutenant and several soldiers who had trusted his judgment. Olluco survived, but the banner was lost, the retreat became a rout, and the survivors called him brave in the same voices they used to avoid saying he had been wrong. He abandoned the army and disappeared into a high valley, living as a hermit among wind-carved stones. Years alone have not made him peaceful. They have merely taught him to bury his anger beneath chores, silence, and a refusal to call himself a hero. When violence comes, however, the old battlefield still wakes inside him, and his rage is less a roar than a door being opened.
