All through time, a balance has existed between Light and Darkness, represented on two sides of the same coin. Neither one ever dominating the other, but always at war for control through their two avatars. Gray and Ren's destinies were set in stone when they were brought to the Realms of Light and Darkness. Both were trapped in Realms that would test their limits and change them at their cores. Gray is trapped in the Realm of Darkness, where his newfound magic slowly eats away at his body. In his dire circumstances, he makes a deal with the Queen of Darkness in hopes of a cure. However, the method of his cure will make him face a past that he has yet to know. Ren is trapped in the Realm of Light. His body and soul fused with the guardian spirit, Byakko. Together with his help, Ren is trying to find a way back to Gray while being hunted by the Queen of Light. Though will he get the perfect reunion that he is hoping for? As time passes, so will they. A dark force is intent on seeing their plan come to fruition. But will either of them be prepared to stop them? Or does fate have something else in store for them?
