Cornu are a bipedal species with rather small bodies and large, round heads with one or more horns. The number, length, and shape of horn varies from individual to individual. Most Cornu have between 1 and 4 horns, but some species will grow dozens.
Cornu horns are most often cone-shaped and quite short, but some cornu grow horns that are longer, curled, and/or jagged. The color and texture of these horns is typically consistent with the color of their skin.
Cornu look largely the same in terms of coloring; they are generally some sort of off-white hue, and do not have naturally occuring patterns like spots or stripes. Their eyes are very large and can be all kinds of colors, but are most commonly dark red, dark green, dark purple, or dark blue.
