A cardinal, named after a bird whose male is known to sport bright-red plumage, is an individual with a position of high authority within certain churches. The Fat Friar, who was executed by his church for certain wizarding activities, resented in his after-life as a ghost that he never attained this position.
Behind the scenes
- In the real-world, cardinal is a position in the Catholic Church and the Church of England. Within the Catholic Church, once the Pope dies, cardinals are tasked with electing a new one among themselves to replace the previous title holder.
