For my campaign i built a new faction to coincided with the story but now i'm having trouble creating a Hierarchy for the faction its a order solely based around the members all being arcane spell casters ,and not counting anyone who multiclasses into one of the classes what would be a good ranking of them also i'm not above using outside names such as hedge wizard , or warlock? Looking for some opinions on where to go from here we aree also in the inner sea for a frame of reference.
so far i'm thinking from the bottom up
Hedge Wizard
Wizard
Sorcerer
Magus (being the top rank)
