Four Great Wolf Packs

From Tardis Wiki, the free Doctor Who reference

The Four Great Wolf Packs, also called the Four Great Houses were the ruling houses of Vulpanan society during the planet Vulpana's Golden Millennium. Made up of pureblood Vulpanan werewolves, each of the four houses was devoted to and changed with one of Vulpana's four moons. The House of the First Moon turned with the First Moon, the House of the Second Moon turned with the Second Moon, the House of the Third Moon turned with the Third Moon and the House of the Fourth Moon turned with the Fourth Moon.
