Would you be willing to sacrifice everything for a promise?
After the disappearance of her cousins, the only clue that Mia has of their whereabouts is a vagabond that lines between madness and cynicism, who claims to be able to take her to where her cousins are: The Sacred Island.
Mia and Leo, her skeptical friend, embark on a trip to an island that defies the boundaries between the real and the imaginary, where Mia is forced to face the secrets of her past.
Nothing could have prepared them for what they found on the island: the chaos of mankind has endangered the kingdom of the elementals, so Mia has to make decisions that will take her to people, beings, and places never seen before, in an attempt of saving the planet from its own destruction.
