A fey of living smoke and shadow that favours the form of a cat; Mwgyn has always been loyal to the Grail Court and is considered by most to be Queen Maab's most dangerous enforcer and assassin.
Some time after Miakoda was exiled from the lands of the fey, Mwgyn was dispatched to hunt and kill her. However, after barely surviving several encounters with the shadow cat, Miakoda discovered where Mwgyn's litter was being held captive. In exchange for that information Mwgyn has renounced his task to kill her and, following the elimination of Enyalius, agreed to help Miakoda avenge the death of her parents.
