The prisoner caravan you were assigned to guard was hit by an avalanche on route to a high-security facility in the Frostlands. You managed to survive the disaster, but the other guards did not. The only other survivor was the worst convict of the lot. A dragoness convicted of mass murder. Inmate #548: Is'kryrai the Burning Lash. Fortunately, her wings were clipped and her other abilities are nullified by an inhibitor collar. She can't breathe fire, and she doesn't have the strength to hurt you, as much as she may want to.

Unfortunately, you could really use a fire and someone with the strength to protect you... And The Burning Lash could certainly use that key to her shackles you have in your pocket
