The Celebrant had also, upon encountering Osiris within the moon, killed Sagira, Osiris' Ghost, making Osiris mortal.

During the final mission during Season of the Hunt, Coup de Grace, the Guardian and Crow located the High Celebrant and used the lure to bring it to the Cryptolith in the Dreaming City. After a chase, the High Celebrant was trapped by Crow, who prevented the High Celebrant from escaping from the Ascendant Plane by blocking their portal, allowing the Guardian to defeat the Celebrant within the Ascendant Plane, making their death permanent.
