Garnet is the Duchess of the Lake's 19-year-old son. Described as being flighty and self-centered, Garnet plays a minor role in the Jewel as an occasional character. He has been known for looking down on the surrogates and thinks highly of himself.
He is described to be extremely attractive, and this is probably due to the Color Augury that the surrogate who bore him used. He has blonde hair and green eyes.
