Her recovery uncertain after a brutal battle, Rivia's thoughts wander to when she awakened long ago. In the dreary underground halls she's confined to, Rivia learns a grim truth-that she's to be a mindless puppet meant to further her addo's ambitions. But by the time his scheme falls apart, Rivia is utterly broken-tormented by the voices of those she was forced to kill. Before she can begin her journey of healing, her new companion Kuifa must help her back on her feet.
