The Parvis Family, also known as House of Parvis, is one of the four dukedoms in the empire. When a daughter of the grand duke comes of age, she will be granted the power to communicate with the Great Water Elemental Beatrix, so that she may bring rain to the barren lands that had been cursed by the Demon Race. They are the only family that owns a private order of knights and they retain a neutral position.

When a child of the family reaches the age of 18, they are appointed as the Captain of the Parvis Knights for three years. Normally, it is in name only as they hand their authority over to the Vice Captain.
- The surname Parvis means "fortunate, victorious".
