After Kelvin's forces are bolstered by the addition of the daughter of the late Demon Lord Gustav, the party sets out for the Country of Water. There, they encounter…the Heroes of Deramis?! With the promise of combat near, our favorite battle junkie waits in anticipation for the clash with the Heroes—and if a few bandits get in his way, he'll just have to “play” with them too! Join this black-clad warrior and his allies as they continue to make a name for themselves in the third volume of an epic journey!
