There's a large amount of Academy students who have already activated, leaving Rohesia in the minority when it comes to being natural or supernatural. She doesn't care if she's supernatural; in fact, she actively avoids having tests done that might prove she could activate, and focuses instead on things that bring power to the less supernaturally inclined: notably, book learning. Still, her apathy towards the suffering of her peers isn't common in the natural populace...
Rohesia finds great pleasure in tending to the exotic plants that are grown inside of the greenhouse, and she shadows the groundskeeper to ask him questions about their care, when he's available to be shadowed. If she isn't in the library, she's amidst the plants, talking to them in her native tongue and making friends with Mr. Turtle.
Plants might be her hobby, but learning is her passion. This teenage philomath spends the vast majority of her time holed away in the library atop the union building, reading books that most teenagers have no reason to be reading. She's learned all she can about the various supernatural archetypes and other common-knowledge stuff, as well as the War of Brothers, plants in other worlds, and esoteric knowledge about cults, covens, and individuals.
