In a world teeming with mythical races—dragons, vampires, elves, and more—Pyris Obsidian finds himself reborn as the Champion of Lilith, the Goddess of Lust. Armed with her divine blessings and an ancient Obsidian bloodline, Pyris is thrust into a deadly world where power is the only currency, and ambition can turn men into gods—or their prey. The empires of Argos teeter on the brink of chaos, with Immortals lurking in the shadows, and gods watching from above, waiting for mortals to fall. As Pyris rises, so does his influence over the magical world, manipulating power, desire, and even reality itself. But the gods and their champions won’t stand idle while a new force of lust and dominance rises. With forbidden magic, unparalleled charm, and an insatiable hunger for conquest, Pyris must navigate treacherous alliances, deceitful enemies, and seductive allies, all while keeping the truth of his destiny hidden. For in this world, desire is power, and Pyris will stop at nothing to claim what is his—even if it means defying the gods themselves. Will Pyris bend the world to his will, or will the forces of the divine bring him to his knees? Only time will tell, as he embarks on a journey of lust, magic, and unrivaled ambition.
