Ruhr is small, slender, and hollow-boned, with much of his apparent bulk being a trick of his colorful feathers. He has a noticeable limp in his right foreleg. In the air he is an agile and darting flyer. He has longer feathers in his mane and at base of tail that are emotionally expressive. Ruhr's head is covered in feathers, and his legs have a sparse covering of small feathers.

He is very birdlike in his appearance - quick sharp movements, feathered wings, leaps easily into flight. He has an aura of moonlight that surrounds him after dark.

Color: Depending on the phase of the moon, Ruhr will be sunset colored or grey(ing) with sunset colored feathers, markings, mane, and tail. He grows more grey as the moon waxes, and reverse greys as it wanes. He also ages with the moon, appearing as a young adult at the new moon but very decrepit at the full moon.
