A roan horse.

Faran is "a great roan horse", the mount of Sparhawk in the Elenium and the The Tamuli series of books by David Eddings. Faran is famous for his bad temper, but this may not be entirely his fault. In one of the later books, the child-goddess Aphrael tells Sparhawk that Faran only has a bad temper because he is trying to please Sparhawk by matching his personality. Much to Sparhawk's annoyance, Faran has a habit of prancing whenever Sparhawk rides him with his formal armour on.
