38 parts Ongoing In a world where the seas are ruled by pirates and haunted by sirens, James Potter and Remus Lupin embark on a perilous quest for treasure, only to fall victim to the enchanting songs of the Black brothers, Regulus and Sirius, who drag them beneath the waves. But fate has other plans. As two rival pirate crews-Lily Evans' fearless band of women and Barty Crouch Jr.'s ruthless crew-clash over the search for the sirens, deeper alliances and unexpected loves begin to form.
Barty, obsessed beyond reason, falls for the captivating siren Evan Rosier, while his twin sister Pandora finds herself drawn to Lily. Meanwhile, Regulus and James, despite their differences, forge an unbreakable bond, just as Sirius and Remus do. As tensions rise and their journey leads them to the Black family's dark secrets, Orion Black unleashes an army of sirens and sea creatures to destroy them all.
In the final battle, blood is spilled, hearts are shattered, and Evan loses his life-sending Barty spiraling into madness. Keeping his promise to Evan, he does the impossible: he burns the ocean itself. With the war over, the survivors struggle to rebuild their lives. James remains devoted to Regulus, despite his siren nature. Sirius and Remus refuse to be parted. Pandora and Lily embrace their love, while Alex gives up his mermaid existence for Mary, leaving piracy behind to build a new life.
But Barty is lost to his grief, consumed by vengeance and destruction. His rampage leaves him imprisoned, broken by the weight of his own actions. The sea may have burned, but love endured-even in the darkest depths.
