Amber Lead

Amber Lead was a white ore that was found only in the country of Flevance.

Overview
Its fabricated products all give off a white shiny coat that made the material an instant success and a practical gold mine for the country, proving wealth and riches for the people. The products made from amber lead vary from wall paint to pottery as well as make-up and weapons. The ore is also used up by plants, giving them its white color.

This lead to the country being nicknamed the White City and its population living wealthy lives, but ironically enough, the ore was the cause of the downfall of Flevance. Over a century ago the World Government discovered in their geological surveys of the island that the ore became slightly poisonous when exposed to the surface but they and the royalty of Flevance decided to keep it a secret from the public because of the wealth it brought, allowing amber lead to accumulate over the years.

Even more ironic, is when neighboring countries started to shoot down any infected Flevance citizens who tried to exit the country's quarantined borders, the Flevance citizens have more lead bullets than they ever needed to retaliate. This led to a war, which ended with Flevance's destruction.

Amber Lead Syndrome
Amber Lead Syndrome (珀鉛病) is a non-contagious, but hereditary, disease caused by the accumulated build up of amber lead in the victim's body after constant exposure to the ore or material products created with amber lead. Amber lead poisoning is unnoticeable in its early stages when it is in low concentration but its effects were observable given that each passing generation were given shorter lifespans. This is due to the fact that the level of amber lead concentration in a child is obtained from its parents leading to everyone in Flevance having the same but accumulating concentration of amber lead poisoning over a few generations. By the time around the Golden Age of Piracy, the poison has accumulated to the point of a generation where children will die before coming of age and leaving any descendents be born.

When the concentration reaches worrying levels, signs and symptoms of the disease are easily visible on the victim. White blotches of skin will appear on the victim's body and their hair is bleached white. They also feel chronic pains all over the body where the white spots are, causing much suffering until eventual death. Because of the fact that everyone in Flevance have the same level of amber lead poisoning, everyone were dying at the same time causing the disease to be mistaken as a contagious disease and lead to the island's ruin. The doctors of the island were helpless in stopping the disease, though Trafalgar Law's father, the best doctor of the country, was adamant that a cure is possible since the disease is not contagious.

Although Trafalgar Law, the sole infected individual to escape the island, was destined to die at age 13, he proved his father right by obtaining a cure and lived to this day, at age 26.

Trivia

 * The amber lead is quite similar to Asbestos, a highly profitable mineral that was once used all around the world, and can be found in all kinds of goods. But use of asbestos was discontinued when it was discovered to cause serious and even fatal diseases. And much like in the case of the amber lead, many governments initially ignored the scientific and medical reports about asbestos's toxicity, continuing to allow its use into the 1980's, while the negative effects were demonstrated since the 1890's.
