Cold and alone, Dartello awakens in an aquatic cavern. As he fumbles in the darkness looking for an escape route, he suddenly hears a woman whisper, Your world is ending. It is not long before Dartello learns he has been chosen to save not only his own world, but the entire universe from an impending threat. If he is successful, he will be a hero.

Called upon by Peacemaker Harmony, a deity, he enters a binding contract, signed in soul, swearing obedience to her. Before he even leaves the cave, his battle skills are tested as one opponent after another surfaces from the water. Now as he faces countless challenges that tax both his heart and his sword, Dartello knows that he is destined to become more than just a man. As the Phantom army declares war and ravages the countryside, Dartello is just steps behind. With everything at risk, Dartello soon realizes he possesses the only weapon capable of saving humanity. A dying world is counting on him.

As battles rage like never before, the future of the world hangs in the balance. Only time will tell if a lone warrior can save humanity before it is too late.
