The Consecration Ceremony was a religious ritual of the Ssi-ruuk, and one of fundamental importance to Ssi-ruuvi religion.
According to Ssi-ruuvi religious beliefs, if a Ssi-ruu died away from Lwhekk, their soul was destined to wander the universe without end, and be denied access to the fourth egg that was the Ssi-ruuvi afterlife. To counter this, the Priests would conduct an hour-long ceremony to consecrate another planet. At the end of the ceremony, the Ssi-Ruuk would dedicate the planet to the Ssi-ruuvi Imperium, and give it a Ssi-ruuvi name.
The only consecration ceremony viewed by non-Ssi-ruuk was when Bakura was consecrated by the Keeramak, during the Ssi-ruuvi attempt to re-conquer Bakura. Interestingly, the Keeramak itself led the ritual, which should have been done by the Priests. It is possible that its unique status in Ssi-ruuvi religion allowed the Keeramak to consecrate a planet. It is also possible that consecration was a province of the Shreeftut, as the Keeramak was the Shreeftut of the Ssi-ruuvi Imperium at the time.
