"We harvest much through effort and ambition, only to lose it when we overreach and grow greedy. Gains hold little value when they are born of obsession, and relinquishing some of them is an unavoidable sacrifice for survival and continuity." The devastating aftermath of the queens' clashes has left the major marine empires exhausted and fractured. This massive power vacuum allows a long-shadowed, predatory race to step into the light: the Sirens. Unlike the mermaids or the Gharaniq, the Sirens possess a dark, deeply hypnotic, and destructive vocal magic. Having waited for generations in the deepest abysses, they now mobilize to claim total dominion over the Seven Seas, threatening an era of absolute psychological subjugation.

Luj, now a battle-hardened figure bearing the heavy weight of the previous oceanic wars, must face this terrifying new threat. The story shifts from a war of physical armies to a psychological battle against obsession, unchecked greed, and overreaching ambition. As the Sirens' mesmerizing song echoes through the deep trenches, Luj and her remaining allies realize that complete victory is impossible. Survival and continuity now require making painful, irreversible sacrifices, forcing them to relinquish the very power they fought so hard to obtain. It is a haunting, high-stakes chapter that perfectly sets the stage for the ultimate fate of the marine world.
