Captain Twayblade was sister to Perigord Sinistra, and a member of the Long Patrol under the rule of Lady Cregga Rose Eyes. She was known as a skilled fighter, her weapon of choice more often than not a rapier. She fought at the Battle of the Ridge of a Thousand alongside her brother and the other woodlanders against Damug Warfang's Rapscallion Army. It is presumed that she returned to Salamandastron with her brother after the battle.
