It is possible, especially for the older Magi, to be a member of multiple Orders.
The Order of Artificers – The engineers, enchanters, and builders of the magical world. They can create all manor of magical Constructs: machines using Mana Batteries to perform tasks. From our handy Mana Phones, to the magical elevators, to our sky ships, an Artificer dreamed it and created it.
The Order of Delvers – Delvers are the adventurers and explorers. They spend a great deal of time traveling the world of Avonlea. Some record it’s history and stories, others search for ancient artifacts or ruins, while others learn of magic the Orders don’t yet have.
The Order of Druids – Druids are in tune with all aspects of nature. From saving and replanting a forest, to taming or hunting wild beasts. They quite often collect the necessary spell components for the rest of the Orders.
The Order of the Golden Leaf – This collection of Doctors, Therapists, and Apothecaries can heal just about anything. Rumor has it they can even bring someone back from the dead.
The Order of Prognosticators – Prognosticators are powerful psychics, adept at learning the secrets of the world, either directly from the mind or vision from the ether. The Prognosticators are the ones charged with finding powerful magics so that they can be recruited into the Academy. (edited)
The Order of Chivalry – These Knights are often referred to as Battlemages. They use their magical abilities in conjunction with their fighting abilities to become a living weapon. They are tasked with protecting the Orders and Avonlea and are often paired with the Delvers while out in the world or sent to protect groups of Mages on missions. They are the experts when it comes to fighting the Wasted.
The Order of the Black Flame – These keepers of the Dead are charged with caring for those that are no longer among the living. They are careful to abide by the various traditions and different cultures in doing so. They are also called in to perform Seances and Exorcisms of spirits that refuse to pass on, or to cull an undead army. They also staff the Temple of the Divine at the Orders.
The Order of Curators – These Mages are often referred to as Librarians, tasked with the care and upkeep of the vast Libraries and magical artifacts collected by the Orders.
