Essence

Essence is an extremely scarce, difficult to work and extract material. It is used as a substitute of steel. An object created with essence is unbreakable, extremely light and is not affected by the pass of time.

Essence is only found in the northern region of Medeia, raising from the soil in the form of gas that needs to be captured in its raw form and then transported to the facilities where it will be liquefied and cast in the desired shape. The slightest impurity in the extraction, or introduced during transport or casting causes the forged object to break in the moment of taking it out of the cast.

Due to its complex manipulation. Even the smallest item made of essence costs hundreds of gold pieces. Exportation is forbidden by the government and only smugglers or royal sanctioned deals can transport objects made of it to the outside.
