But it was all taken away from him in a single night by his own traitorous brother, who murdered his fiancée and destroyed his whole life, turning the world against him. Now, he lies poisoned and dying beneath a random tree in an unknown place. He is broken, both physically and emotionally. But even in death, he refuses to give up. He vows to rise from the ashes and claim his revenge. If need be, he would complete his revenge in the next life, and the life after that, and the one after that.

As he gets closer to the truth, he realizes that the stakes are even higher than he thought. The fate of the entire universe hangs in the balance, and it will take a massive toll to save it. Will he be able to overcome his demons and fulfill his destiny? Or will he be consumed by his own hatred? The answer lies in the stars... This novel contains LGBTQ+ characters, but the MC is not one of them. Note: The first thirty chapters are not my best work and contain much exaggeration for the point of setting up the plot, so do not take their quality as the overall quality of the novel.
