Beryl was born in Mirwell Province. She has long wanted to restore Mirwell to its former glory, albeit in an honorable, non-militaristic way. She fought hard as an officer in the provincial army to secure a place as Mirwell's closest aide. She has considerable experience as his chief interrogator. It is from this position that King Zachary has her planted as a spy to keep watch on the Mirwells, instead of running messege errands, as her ability it to deceive and convince someone of a role she portrays. Beryl is the one who slipped F'ryan Coplebay the message about Mirwell's plan to amuch the King's annual spring hunt and Amilton's coup.
