Adamantite

Adamantite is a mineral. It is used in weapon and armor development, as well as tools. It is occassionly used in objects, but due to it's excessive price (Equivilant of ~$120,000 USD), it's mostly only used by those who can create or obtain it.

It is obtained from the shell of a Gui, a turtle that resides in the eastern sea of Arapa. It's protected by the governements of the areas surrounding the sea. The Mineral is taken from the shell by a chemical reaction.

Posession of it is illegal in Ceveria without a proper liscense.

In the events in Lucia, Scott was carrying a pair of adamantite gaunlets, and a nugget of pure Adamantite. He was charged with illegal weapon posession, and illegal posession of the nugger, but the charges were later dropped.
