Bronwyn

Probably born to be a teacher, Otto's adopted-sister Bronwyn decided from an early age that her goal in life was to give every child in the isolated valley where the two siblings reside a proper education. Being kidnapped has thrown a considerable wrench into these plans, and being separated from her younger brother, the apple of her eye, has left the usually altruistic and patient young woman in a foul mood that she won't hesitate to visit upon her captors.

Spoiler

She is Brandy's sister and her real name is Bryony.
