In Olympus Academy, the first and only school to house Filipino demigods and mythological creatures, students are divided into four classes: Alpha, Beta, Gamma and Omega. Carrying one of the titles comes with great responsibility, especially to Reign, a girl who continues to live through the privilege and burden of being an Omega. All eyes are on her class as a new student arrives, bearing a legend that many do not believe and some, refuse to. Reign decides to dive deep into the legends of Olympus Academy, in efforts to understand their new member, and eventually she will. She will come to know two cruel truths about their very existence: Mythological creatures like her are being hunted for power. And as for the demigods who belong to the same class as her, they were a consequence, a threat, an ultimatum of what was once destined. To be the hunted or become the hunters? To be the protectors or become the protected? The Omegas need to make a choice. But being descendants of the original Omegas, demigods who defeated gods, titans, and even overcame Chaos, the first deity to ever exist in mythology... They know they're just as powerful to choose another option that's not given: Become no one but themselves.

To become no one but themselves, the Omegas must journey to the deepest realm, a land of darkness where not even their parents have traversed, where no god besides those who have fallen exist. The entire world rests on the outcome of the on-going war of hearts and the Omegas have yet to know the ultimate cause of this complete chaos. The source. The beginning of all. Power. Control. Those who must rise are destined first to fall. The scale of good and evil is tipping to uncertainty and it's only a matter of time before it breaks. As the forces of the heavens and earth collide, the Omegas will be tested beyond their limits. Soon, they will learn that just like the generation before them, they are bound to make their own story, carry out their own legacy. A legacy so legendary, they might just be the last to ever be written. And with Reign at the heart of the chaos, her strength and conviction are all that stand between salvation and destruction. Will she find the power to overcome? Or will she become just another casualty in a world so consumed by its own ruin?
