Ursun, also known as the Great Bear, or Father Bear is the God of Bears and Strength and the patron god of Kislev. His worship was first introduced by the Gospodars, but bears are such a major part of Kislevite life that the religion was absorbed almost instantly. Bears continue to be a vital part of society to this day, and the religion is now inseparable from the Kislevite culture. Worship of Ursun is not a state religion as the worship of Sigmar in the Empire is, but the fate of Kislev is linked in many minds to the fortunes and favour of Father Bear. The Cult of Ursun is the main religious organization that mandates the worship of Ursun.
