It's a simple hierarchy:
* Archon: The divine ruler of the Faith - has control over the management, dogma, and teachings of the faith. A micron who has this position has the honorary "Qon".
* Templar: Leader of a specific region of the world for the faith.
* Cleric: A minion of a specific temple. May specialize to a particular quintesesnce or god.
* Acolyte: Cleric-in-training.
If there is still an Archon, this has to be Bill Dusch or Harvey. What I'm sure about: we have no Templar for the Sermolotian or Kildarian region.
