The Chaf family, which was also styled House Chaf in Basic, was the Fifth Ruling Family of the Chiss Ascendancy, being one of the group of affiliations known as the Ruling Families which provided leadership for the Chiss people. In keeping with the Chiss custom of indicating an individual's role by the color scheme of their clothes, members and retainers of the Chaf family wore yellow costumes, ranging from ornate formal robes to utilitarian jumpsuits depending on their rank and duties. They controlled the planet Sarvchi.
