Elemental
Elementals are creatures that are mostly or entirely composed of elementally aligned Aura. They can be found both in the wild, especially in areas rich wiht ambient Aura, or constructed by summoners, and are then aligned specifically to one or more of the elements the summoner possesses. Naturally formed elementals have a limited will of their own, but mostly fall under the control of a local Kami associated with the element said elemental is composed of. Constructed elements are generally directly controlled by their summoners, or imbued with a degree of autonomy by more advanced casters.
