Roux's eyes shine a bright silver color, though the beautiful monochrome pieces give him no vision while the sun shines. Roux has a very special case of blindness, in which he was born without cone cells. Only his rod cells function, giving him nocturnal vision. His world is painted in shades of grey, like his eyes, but during the day when it is gone, the stallion can still sense the motions around him. Roux has a solid, twisting horn of ivory bone material that spirals from the middle of his forehead, the same white horn of his mother.

Roux started out as a generally carefree colt, growing and playing and learning alongside his twin brother. However, he had always been the more timid of the two, especially during the day. He stuck close to his parents' sides when he was most vulnerable, learning many stories from his mother. Kou always had a way to encourage and strengthen him and never let himself feel bad for being blind--she never let the foal see it as a handicap. Despite that, Roux was always gripped with an undeniable sense of reality--he could not do everything the others could do.

When he was still young he was captured by Smoke of the World's Edge and kept for months. His mother and twin brother, Sacre, were also captured. Roux had met Smoke on the beach only weeks before and had thought of her as a friend. However, she broke his trust in her. Since then, Roux has not and will not be able to trust easily--he feels he can only trust his brother, Sacre, and his mother. A bitterness and hatred for the horses of the Edge boiled in his gut while he was held captive there and it silenced his tongue. Since his capture Roux has become a more dark, solemn creature of few words. He has also dedicated himself to learning the ways of combat so that he may protect himself from ever being captured again, and he may protect Sacre from that fate as well.
