A High Priestess is a High Fae who oversees religious ceremonies and rituals. They also record the histories and legends of the Fae, and advise the lords and ladies in matters great and trivial. There are twelve High Priestesses in total who govern all the priestesses across Prythian, many of whom reside in the Dawn Court, Day Court, and Winter Court.
According to Lucien, the priestesses get their magic from their ceremonies, and can be utterly lethal should they choose to be.
Priestesses are allowed to marry and bear children as it would dishonor the Cauldron's gift of fertility to lock up their instincts. They have great power in the hierarchy within Prythian, and their children are typically powerful and well-respected.
They wear billowing, artfully twisted and layered robes that are pale blue-gray in color. The robes are far from matronly.
In A Court of Mist and Fury, Rhysand says that the High Priestesses have burrowed into a few of the Courts - Dawn, Day, and Winter mostly. They've entrenched themselves so thoroughly that their spies are everywhere and their followers are near-fanatic with devotion. And yet, during the fifty years of Amarantha's rule they escaped and remained hidden.
