Hierophant of the Comet

Hierophant of the Comet
The number of hierophants is fixed at twenty-two on any one world, one for each card in a Deck of Many Things. As a group, hierophants are sometimes called Sages, but each hierophant is also identified with a particular card. When a hierophant dies, the remaining leaders choose an initiate to fill the position, preferring initiates from the oldest broods.
A new hierophant undergoes a rite similar to the rite of initiation, but only the other hierophants are present. As the cosmic narrative unfolds, the new hierophant is inducted into the esoteric secrets of the group's leadership. The rite concludes with a mind-shattering vision of the Void, which hierophants understand to be the formless nothingness that preceded the creation of the cosmos and will endure past its destruction.
The leaders of the Heralds of the Comet, hierophants are powerful warlocks with mighty spells at their disposal. They can commune with the alien mind of the All-Consuming Star, blast enemies with beams of eldritch energy, and conjure manifestations of this entity to devour their foes.
