Crusader Riona Grady was a human member of the Vigil. She once served the Ebon Vanguard in Ebonhawke in the same unit as Dougal Keane. The unit had left her to search for treasure, leaving Riona to be detained and questioned for treason. Later, she was sent to a work camp for her "crime." After her sentence, she left the Ebon Vanguard and joined the Vigil, hoping to find guidance.
She was ordered to search for Dougal Keane and convince him to help aid her and Ember Doomforge in recovering the Claw of the Khan-Ur in the ruins of Ascalon City. Once the Claw was retrieved, however, she betrayed the team and stole the Claw with the hopes of making the Flame Legion stronger again in order to re-ignite the old civil war among the charr. She did this hoping the Ascalonians could gain the upper hand in their own war with the charr. However, she was killed by Dougal before she was able to accomplish her plans.
