Vaida is a disgraced former Wyvern General of Bern, leading her own unit of wyvern riders, known as "Vaida's Raiders". She lost everything after her troop was ordered to attack a group of innocent peasants, who were said to be rebels of Bern.  After refusing and trying to end the slaughter of innocent civilians, she and her troop were charged with treason. Most of her unit were hanged, but a few, including Heath and Vaida, survived. After that event, she eventually fell in with the assassin group, The Black Fang. She is extremely dedicated to Zephiel, the young prince of Bern, and is confident she is a good protector of him. She is prone to bragging and boasting of her abilities and talents.
