Born in the world of war between frost and fire, Laith Zurlyn found herself in the middle of chaos and disaster between Invera and For. Unknowing she was more than what they called Forbiddenchild, as she can carry the dark soul, Varynx, inside. The perfect vessel. Little of knowing the true power she held within her soul; not a gift, but a curse that took the form of a shadow, lurking, waiting for an opportunity to conceal itself. That power alone could help her fight for both Frostland and Fireland, yet there was a risk that could change her to be the deadliest weapon. Terror of her own gifts, she buried it within; far from the knowing of the real leader of Ren and the highest courtiers that lived on the Ruin as their last destination. Nowhere to turn, Laith had rallied with the frost to end the reign of King Ryu, the tyrant Frostking. To save Alra, the For girl with a gift of light, she had convinced the mysterious Ren who helped her that the healer might be their key to end this war once and for all. Then, she had to be brave enough to face the devil who was the mastermind behind all the mayhem of the kingdom; putting an ending to the real war between the Guardian before it even began.
