Transmutation Circle



Transmutation circles are the basis of all alchemy, the circle works by providing a medium with which the alchemist can circulate energy between the alchemical source and their body, this allows for alchemy. In the Anime the source for alchemy is the movement of souls through the gate. In the manga amestrian alchemy is thought to originate from the earths natural tectonics but may in fact be the homunculus known as "Father". In the Eastern country of Xing the alchemy source is the flow of life. Alchemists who have seen the gate and know the truth can use alchemy without a circle by using their body to create one (examples include Edward Elric, Izumi, and Alphonse Elric and Wrath in the anime using his right arm and left leg). The ancient civilization of Xerxes was destroyed when a giant transmutation circle was used to transmute the souls of its slaughtered inhabitants into the Philosopher's Stone. Recent events in the manga may mean Amestris is destined to share the same fate.

Transmutation circles can be personalized for different purposes or for easier transmutation. An example of this is the transmutation circle on Roy Mustang's glove which allows him greater control over fire but limits him to using fire. Another example is Solf J. Kimblee whose hands are tattooed with circles specifically designed for transmuting material into explosive substances.
