Flevance

Flevance, also known as the White City (白い町), is a country in the North Blue where Trafalgar Law was born. It is known for its Amber Lead.

Past
The island was said to be straight out of a snowy country in a fairy tale, as the earth, trees, and grass were all pure white, and the beauty was so stunning that it caused visitors to question whether the island was real or not. A special and rare kind of lead, Amber Lead, was discovered underneath the kingdom, and was determined to be the source of Flevance's marvelous white nature. With the discovery of amber lead, all kind of goods such as utensils, paint, sweets, makeup and weapons were made of amber lead. People from all over the world brought the high quality goods made from amber lead, and quickly enough, the kingdom became wealthy thanks to the lead.

However, a hundred years before the industry came to be, the World Government and the royal family discovered that amber lead was poisonous, but chose not to inform the country of its' dark nature, as to gain profit from the industry. By the time the world discovered of the toxicity of amber lead, it was too late to save the heavily poisoned country. All of the citizens became sick at the same time, and died. The neighboring countries, fearing that the disease was contagious, quarantined the island. The citizens of Flevance, desperate to leave the kingdom, attempted to fight their way out, and the neighboring countries, with justified cause, killed the citizens, and destroyed the kingdom. Trafalgar Law is the only survivor, as he managed to smuggle himself across the border by hiding himself amongst a mountain of corpses. This blatant disregard for the country's life turned Law into a bitter child who sought to destroy the world that destroyed his with what little life he had left.

Trivia

 * Flevance may have been based on Casale Monferrato, due to similarities between the two places, which includes the sharing of the same nickname, "The White City", production of unknown toxic minerals into goods, asbestos for Casale Monferrato, and Amber Lead for Flevance, and in both places, thousands of people died from diseases caused by the toxic minerals.
