From G.G.Kay's Fionavar Tapestry, The Wandering Fire (book 2);The raithen of Daniloth were to horses as Gods were to men. They were golden as the setting sun all through their bodies, but the head, the tail and the four feet of each of them were silver, like the not-yet-risen moon. Their eyes were fiercely blue and shining with intelligence, and Ivor loved them on the instant with all his soul. And knew that every Dalrei did the same. (...) "How many do you have?" he heard Cechtar breathe."These two and three others. They do not breed since the war against Maugrim. Too many of them died. Something changed in them. When these five are gone, no raithen will ever outpace the wind again." Lydan's voice was a chord of loss.
