Order of the Elements
The Order of the Elements was founded by Drake, Orion. Mathis, and Ultimo, and their fancypants tunics caught the eye of other denizens of the land, attracting other members. Today, its membership remains fairly small, but once its founders encounter mundane circumstances that allow for more travel, it will likely expand.
It is also at odds with the Brotherhood of Azor household, also of Crimson Wood.1
Is years old with most house identifying garb (and members, really) missing or forgotten somewhere. Drake still wears his OoE tunic like a champ.
