Cavendish (キャベンディッシュ Kyabendisshu ) is the surname of a prestigious and aristocratic Witch family from Britain with a history dating back to the 6th century. They are highly respected and have great influence in the magical world. Their family estate is the Cavendish Manor, located in Wedinburgh. The Cavendish line of witches is known both for their wisdom and their kindness. Their motto is "Affection" and their patron animal is a white unicorn. They specialize in healing magic.
From the Middle Ages to the last war, the Cavendish used their magic to heal people regardless of whether they were allies or enemies. They kept these practices secret because of those who disagreed with them.
Family leadership has been inherited by generations of witches along the maternal line. This role can only be inherited in a ceremony during a Venusian Eclipse that only happens every many years, and it is said that a horrible calamity falls on all that interfere with the ritual.
Currently, Diana Cavendish being the legitimate heir apparent. However, due to the death of Diana's mother in her youth, Diana's aunt Daryl Cavendish and her mother's younger sister is the proxy head of the household. The period of her leadership has been one of decline for the family. She has little regard for their history and thinks magic itself is obsolete, and she has sold countless precious artifacts held by the family, often at discounted prices. She believes this practice is necessary to sustain the family, unlike her elder sister who helped others for free. Diana, old enough to put a stop to her, selflessly decided to leave her beloved Luna Nova and save the family from extinction by becoming its head. She was unable to complete the ritual due to stopping to save Daryl, but this act of kindness earned her the approval of Beatrix's spirit.
Family members are characterized by their blond hair with greenish highlights and blue eyes. The witches of the Cavendish family tend to inherit great magical talent in their bloodline.
