War is on the horizon.

Fireheart had lost his last life and couldn't make much out of his new one.

Massimo struggled with the fact that he was becoming an evil villain.

Alessandra dreams of leaving home to go on an adventure.

Soon all would run into each other all becuase Fireheart tried to make something out of himself and travel into the labyrinth below King Caravaggio's castle in search of somebody he once knew in his other life.  There she is cursed to forever dance as a human marionette.  But she manages to warn him of an impending attack on the Otherworld.  If he wants to stop the horrid king, he would have to go ahead to protect the Princess Alessandra along with her brother, Prince Giuseppe because it's too late to protect their world.  Being the last Promethean, Fireheart has a lot on his shoulders yet it also helps him because he still has the abilities of his old life.  Before he leaves, the Human Marionette tosses him fire runes to help him only for Massimo to attack.  Firheart makes it to the Otherworld where he has to find the princess and prince to protect them from the war that strangled their land.  Lucky for Alessandra, her wish is about to come true.
