The companion foxes of Farrix, mate of Jinnarin. There have actually been many Rhus over the years, as it is the Pysk way to adopt the kit of a fox companion and give it the same name.

The Rhu who was seen in Voyage of the Fox Rider was left behind by Farrix, and instructed to wait a certain amount of time before going home. He brought a note home to Jinnarin, and led her to Farrix's last known location.

Though he was not Jinnarin's companion, she was fiercely protective of Rhu when Alamar insulted him.
