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 for some time prior to 1319 AE. In 1319, the unit 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" and remained there for two years, after which the Ebon Vanguard still watched her closely and never let her patrol beyond the walls of Ebonhawke. She left the Ebon Vanguard in 1323 and joined the Vigil, hoping to find guidance.
In 1324, the then-Crusader 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.
