Law is the only known survivor of Flevance, a town whose inhabitants suffered from a condition known as Amber Lead Syndrome. Because the disease was fatal and poorly understood, Flevance was destroyed by neighboring countries out of fear, with a young Law barely escaping alive.[7] He subsequently joined the Donquixote Pirates, where Donquixote Doflamingo intended to make Law one of his executive officers.[20] He grows close to Doflamingo's brother, Rosinante, who he calls "Corazon".
