Siren Song

Original story is from an unknown author from Wattpad I couldn't find. I'm just trying to recreate it.

"The Great War had concluded itself, bringing with it an era of peace and prosperity unlike any time period that had come before it. Among the denizens of the Grand Line however, the Pirate King was the busiest of them all; the busiest, but also the one whose time was disrupted the most. This time however, the ambassador whose urgent report required his attention was a most welcome sight.
