The Ssi-ruuk of the Ssi-ruuvi Imperium in the remote Ssi-ruuk Star Cluster had a very old and developed religion. It was controlled by the Conclave, one of the two highest governing bodies of the Imperium. Only gold-scaled Ssi-ruu could join the Priest caste. Ssi-ruuvi religion may have been a tool used by the Ssi-ruuvi elite as a way to control the Imperium.
