Rio is the founder of the Library. She wanted a place to call home, where she could read as much as she liked. It soon grew into so much more. She is also a practiced fighter, though she prefers to heal rather than harm. She is more of a figurehead leader, and prefers to let Democritus take care of the actual leadership of the clan. However, most members of the clan recognize her as their true leader.
Rio is introverted, and prefers to keep to herself. She is kind and thoughtful. She gets excited over small things, and is lively and passionate.
