Akmenon is a broad-shouldered tiefling with deep russet-red skin, swept-back black horns, amber eyes, and a long tail that moves with restless purpose. His dark hair is cut short around the horns, though the front is usually tied back with a faded strip of blue cloth from his old regiment. He wears well-maintained chain mail beneath a scarred military coat that is slightly too large in the shoulders. His shield bears several layers of repainting, and he smells faintly of oiled leather, campfire smoke, and cloves from the cheap chewing spice he favors.

Akmenon is dryly charismatic, practical, and difficult to intimidate. He enjoys soldiers' humor, respects competence wherever he finds it, and has a soft spot for frightened people who pretend not to be afraid. He dislikes ceremonies but remembers every useful detail from them, especially who stood where and who avoided eye contact.

Akmenon was born in a border garrison where tieflings were treated as useful before they were treated as welcome. He learned early that a uniform could make people hesitate before judging him, so he joined the army while still young and became a reliable line fighter. He was never the most obedient soldier, but he was exceptionally good at recognizing when an order was foolish, and at keeping frightened recruits alive when formations broke. His horns, tail, and infernal heritage made him memorable, but his habit of polishing everyone else's buckles before inspection made him respected.
