The Hierophant represents the teacher. The master of knowledge and the gatekeeper to higher knowledge.
No one represents that more than the head of the Druse Academy, High Priestess and Master Luminary, Yamoja. As the High Priestess, they’re responsible for not only the safety of students at the Academy but also for pushing them forward.
The title of Master Luminary is only given to Crystal Priests who have learned almost all the major spells, incantations and invocations related to Azurebending. This usually takes 50 odd years to complete. Yamoja enrolled at the Academy at 14 years old.
And became Master Luminary at 25.
Yamoja is the future, leading the future.
