Rise of the Ruinations (Essence Guild Series) Part B  (English, Hardcover, Avi Nash)

Before the first star falls, shadows shall rise. Before the last light fades, ruin shall claim its price. Before all else ends, a choice must shatter the void. The Door is breaking. The Ruinations are rising. Poseidon Fulminata bears the weight of duty—honor, sacrifice, and a fragile hope that something can always be saved. But hope falters as the Door between worlds fractures, bleeding a void that twists existence and births horrors beyond comprehension. The Ruinations follow—heralds of eternal change and destruction. Watching from the edges is the Masked One, feeding on Poseidon's doubt and despair, driving him closer to collapse. As Poseidon fights this encroaching apocalypse, the weight of his failures and sacrifices begins to crack his mind. His memories falter, his sense of self dissolves, and the Voice of One whispers truths and lies alike. Yet, when all seems lost, Poseidon rises—because he must. Visions of the past and voices of what is to come lead him to the Knights of Oaths, a sacred order protecting the world from a secret to end all worlds. In a war between ruinous creatures and their counterparts, Poseidon uncovers truths long buried—and a destiny tied to a power that carries the omen of death. As the void consumes existence, Poseidon must transcend what he is to become, the Vessel of Beyond—a force of unity and truth sought by all forces. He must choose between preserving the worlds as they are or forging something new, at a cost so great that hope itself may vanish. Against the rising Ruinations and the shadow of despair, Poseidon faces one choice: Will he rise above the Darkness, or will it claim him—and all worlds with him? For when the last shadow falls, one truth remains: the light he carries must save more than he believes can be saved.
