Liosa Custenin née Aeryn is a Sinlarine and wife of Tearlach Custenin. After her and Tearlach's affair led to their respective clans disowning them and turning them into outcasts, they were married by Osmond Cordae Locke who invited them to Ridgefort where they could begin their life anew.
They were trained to use their innate connection to the Void to negate Magic aimed at them by Axikasha Keiran. They entered into the service of Valencia's king as Void Knights. They are suspected to be the most powerful of the ones in his service. The couple have had several children thus far, and Liosa is pregnant again.
