Formerly the Crystal Alchemist, Marcoh was the leading researcher in the creation of the Philosopher's Stone. Tormented by the fact that his research was used in the Ishval War to kill many innocent people, he fled from his position as a State Alchemist and took his research with him to prevent it from being used for further destruction. Hiding from the military and posing as a medical doctor, he uses the Red Stone he created to help the sick.

"In order for something to be obtained, something of equal value must be lost."
 
Alchemy is bound by this Law of Equivalent Exchange—something the young brothers Edward and Alphonse Elric only realize after attempting human transmutation: the one forbidden act of alchemy. They pay a terrible price for their transgression—Edward loses his left leg, Alphonse his physical body. It is only by the desperate sacrifice of Edward's right arm that he is able to affix Alphonse's soul to a suit of armor. Devastated and alone, it is the hope that they would both eventually return to their original bodies that gives Edward the inspiration to obtain metal limbs called "automail" and become a state alchemist, the Fullmetal Alchemist.
 
Three years of searching later, the brothers seek the Philosopher's Stone, a mythical relic that allows an alchemist to overcome the Law of Equivalent Exchange. Even with military allies Colonel Roy Mustang, Lieutenant Riza Hawkeye, and Lieutenant Colonel Maes Hughes on their side, the brothers find themselves caught up in a nationwide conspiracy that leads them not only to the true nature of the elusive Philosopher's Stone, but their country's murky history as well. In between finding a serial killer and racing against time, Edward and Alphonse must ask themselves if what they are doing will make them human again... or take away their humanity.

Alchemy tore the Elric brothers’ bodies apart. Can their bond make them whole again? 
In this world, alchemists are those who study and perform the art of alchemical transmutation—the science of manipulating and transforming matter. They are bounded by the Law of Equivalent Exchange: in order to gain something, one must sacrifice something of equal value. 
In an alchemical ritual gone wrong, Edward Elric lost his arm and his leg, and his brother Alphonse became nothing but a soul in a suit of armor. Equipped with mechanical “auto-mail” limbs, Edward becomes a state alchemist, seeking the one thing that can restore his and his brother’s bodies...the legendary Philosopher’s Stone.

Note: Includes 8 extra chapters.

The rules of alchemy state that to gain something, one must lose something of equal value. Alchemy is the process of taking apart and reconstructing an object into a different entity, with the rules of alchemy to govern this procedure. However, there exists an object that can bring any alchemist above these rules, the object known as the Philosopher's Stone. The young Edward Elric is a particularly talented alchemist who through an accident years back lost his younger brother Alphonse and one of his legs. Sacrificing one of his arms as well, he used alchemy to bind his brother's soul to a suit of armor. This lead to the beginning of their journey to restore their bodies, in search for the legendary Philosopher's Stone.
