Ronan is a mountain of a man who moves with the predator-like silence of a panther. His skin is tanned and cross-hacked with pale white scars, most notably a jagged line crossing the bridge of his nose. He has short, salt-and-pepper hair kept in a strict military crop. His hands, though calloused and thick-fingered, are surprisingly steady. He smells of ozone, iron, and a hint of pressed lavender, a scent that stands in sharp contrast to his brutal exterior. Despite his size, he walks with a light, measured tread that barely makes a sound on stone or wood.
