Caleb's general appearance is best described as non-descript. His unruly black hair is cut short. His brown eyes complement his coppery-brown skin. A scruffy goatee covers some, but not all of a scar along his left jawline; a souvenir from a gang fight in Selanor.

Caleb prefers simple linen and wool clothes; as he wore in Andoc. When necessary, he wears dark leather armour and knee-high boots covered by a mottled-green travel cloak. He carries a shortsword on each hip and a dagger in his boot. A longbow is usually slung on his back.
