Zarya must become the darkness...

Dark magic is spreading and Zarya knows that only she can save her world from annihilation.

In a palace of black marble, she finally meets her father-the mysterious Raja Abishek. She needs his help, but she's wary. For years she was told to fear this man, that he seeks to steal her power.

Rabin is sure that Abishek is their ally. And when the magic binding Zarya and Rabin begins to fail, only Abishek can offer a cure. Does Zarya dare to place their lives in his hands? Can she hesitate, when Rabin could be torn from her forever?

In a ruined and long forgotten city, her love for Rabin will be tested to its limits. An army of shadows is on the march, destroying everything in its path. It's time for Zarya to face the darkness inside her-and release its devastating power.
