The hierarchy of the Ecclesiae ends (and arguably begins) with the Archon, who serves as kind of the magical pope. Obviously I’m not looking for people to play Archon Januarius, so beneath him would be an assortment of cardinals, bishops, and so forth. The inquisitors sort of serve as his personal task force – a service of clerical knights. The Inquisition itself is probably ends at the Grand Inquisitor, whom I have not named at the moment. I’ve kept things really vague and simple so they could be workshopped as we go on, but I think it’s best for individuals to apply for inquisitors of varying powersets. As a comparison point, I could say look at the ranks of the holy knights from Seven Deadly Sins?
