Coach Rohana (last name is unknown) is the Purple (or Ambi) Coach at Exillium. Rohana helped Sophie find out more about Ruy Ignis, a previous Wayward, as well as teaching her many elvin skills during Sophie's banishment.
Previously, the coaches taught in the Neutral Territories and moved campus every day; however, in Lodestar, the Coaches moved to Foxfire to educate the citizens in using their skills. It was suspected that the Council wanted the coaches to teach skills so Elves know how to fight if there was a cross-species war.
Coach Rohana is described to have creamy brown skin and straight, shiny black hair.
