Jonathaen stands at 6'1 with a lean, but well developed build. He is always quick to smile and laugh, almost always amiable and welcoming. His features are reminiscent of a more regal people, due to his ancestry of the nobles of Arnor. His raven hair is often well kept, a contrast from his striking grey eyes. Jonathaen's demeanor is usually cheerful and he is always willing in chime in with a sarcastic, but facetious remark. However, when caught alone, he can appear wistful and quiet, a far cry from his typical behavior around others. It takes quite a lot of provoking to truly irritate him, but when he does, he becomes eerily calm and his grey eyes seem sharp and calculating.

Jonathaen wears a set of leather armor adorned with buckles and straps to help secure his various tools and gear. He carries two blades on each side and a bow with a quiver tethered to his back. His only other attire consists of an old plumed hat and a silver chain necklace. He looks perpetually weather-worn from his incessant traveling.
