Fortuna Rymmer was [[Lord Gabriel Rymmer]]'s only daughter. She had always been a handful, refusing to learn the ways of being a lady. Instead, she preferred to rebel by sneaking out of her room, learning how to pickpocket, and getting into trouble. As a last resort, her parents sent her to the the [[Library of the Cobalt Soul - Port Damali]], which did work, for a time. The [[Cobalt Soul]] helped her rein in some of her impulses and taught her how to fight. She became the Cobalt Viper. However, even the Cobalt Soul couldn't curb Fortuna's independent streak. She eventually broke away and became the master thief known as the [[Black Viper]].
