At first glance, the strongest of his appearance is that of a Kessurian-Ryn hybrid, bearing the tall frontal horns of the former species and their distinct scales and pointed ears. Meanwhile, a long, furred tail winds from his spine, a gift of his Ryn heritage, as is the violet coloration of his skin. Rue bears animalistic fangs and long, flowing waist-length hair, itself shining whenever light hits it, making the violet, scarlet, and gold gradient all the more beautiful. The same coloration is seen on the long, sleek metallic fur of his tail tip, and even on his thick eyelashes and straight brows. Bright goldenrod eyes will occasionally, demurely lift from their downcast state, complimenting pale saffron scales in patterns similar to tiny, tightly clustered petals and leaves, framing his cheeks, cheekbones, and forehead. The scales continue up his horns and down his neck and spine, small patches of the flowers gathered on his shoulders and thighs, graduating to a richer marigold and sweet orange at the tips and outer edges.

Despite his height, Rue stands with a permanent servile stoop, and is severely underweight for his size, skin clinging taut to bones and sinew stretched thin, every single rib, spinal bump, and notch of joints clearly visible, from hip bone to elbows, knees, and fingers. His nails are short and dark and his right arm terminates just below the elbow, the rest of the limb missing. Rue's skin shows no sign of any scarring, save for two sets of silvery brands: runes in ur-Kïaat on his chest, and a scimitar on the back of his neck, underscored by his serial number: SP-FKRD-29-0034991.
