Together, they uncover the Church’s deception and fall deeply in love. When Leviathan sacrifices his soul to protect her, Siren embraces the darkness, becoming the Queen of the Abyss. Driven by love and vengeance, she destroys the false gods and gives up her own heart’s power to restore him. Just as they are finally reunited, a mysterious star map and an ominous awakening in the distant cosmos reveal that an even greater threat is approaching, putting their hard-won happiness, and the fate of the world, at risk.
