In the Rider Waite Tarot deck and similar decks, "The Hierophant" (sometimes called "The Pope") is one of the twenty-two trump cards comprising the "Major Arcana", and represents conformity to social standards, or a deference to the established social moral order.
In the Mythic Tarot deck, the Hierophant is depicted as Chiron, the learned centaur.
Synn is opposed by the Hierophants, rebels made up of native Thanagarians as well as races that Thanagar had conquered over time.
