Elementals are wizards who have the ability to manipulate an element to such an extent that it goes beyond simple spells and charms. There are four known bending arts; all of them bend a specific physical element. The four elemental bending arts are based on the four classical elements, water, earth, fire, and air, and each is manipulated through the wand the Elemental possesses. While bending is traditionally performed through the motions of one's wand movements, certain Elementals are able to effectively manipulate their element with only minimal movement of their wand.
Elementals is a phenomena everyone in the Wizarding World has heard of. They were first mentioned long before Hogwarts was established in the late Early Middle Ages (c. 993). An old witch owned a book which was stolen from her by a bunch of thieves; this book contained information about Elementals, their spark, ability to manipulate the elements and much more.
The thieves went public with this information and they even harrassed the old witch to tell them how to become an Elemental themselves, wanting to be what the book described as "powerful individuals with the ability to manipulate the four elements in ways magic never could". The old witch told them that you can't simply become one of them. Thinking the old witch was lying because she wanted to become an Elemental herself, they tortured her until she lost consciousness. Then they left her alone in her home to die.
With the information now being public knowledge, many witches and wizards didn't believe that Elementals were able to manipulate the elements in ways magic never could. They didn't need to have these powers (which were probably fake since they were written by an old witch). However, some wizards and witches started to consider themselves to be Elementals due to the fact that they were able to manipulate an element with the use of magical spells, completely ignoring whatever the book had said, in order to become famous in the Wizarding World but they all failed.
Throughout the centuries, people started to pay less attention to the myth of the Elementals because there never has been a legit one; many people who claimed to be one were power-hungry people, trying to get attention. This all changed when thousands of people witnessed the prophecy of a famous Seer during the Quidditch World Cup in the 1800s; she was foretelling the destructive First Wizarding War which was nearing fast and that the Wizarding World, which would finally be graced with the first Elementals ever, needed the help of these people in order to survive since only they would be able to defeat the Dark Lord that would soon arise.
Named "The Original Four", the population of the Wizarding World has been waiting for the arrival of the Elementals, knowing that the war the famous Seer spoke of more than a century ago was getting closer and closer. With still no sign of the Elementals, the man who called himself the Dark Lord has been building up his army, preparing to strike the Wizarding World while still keeping an eye out for the Elementals, wanting to destroy them as soon as possible as they are a threat to his path of world domination. Eventually, the Wizarding World began to recruit their own army, not wanting to be dependant of the arrival of the Elementals, thinking that it was all a legend and that they would never arrive at all. Unbeknownst to them, the Elementals are already alive and well. However, the Original Four itself doesn't even know about their own powers and status yet.
Airbending is the bending art that concentrates on speed and evasion, forgoing a strong offense for a greater defense. Though apparently lacking fatal finishing moves, it is the most dynamic of all the bending arts. As the element of freedom, airbenders use their capability to bend unencumbered by the ground or any other environmental factors and use their own momentum as a weapon, evading attacks with astounding agility to tire their opponents out or building up massive inertia for explosive gusts of wind to make their counterattacks finishing moves. Airbenders, when resorting to physical confrontation, are able to harness the immense and intangible power of wind. Airbending's opposite is earthbending and the confrontational style that serves as its foundation. Airbenders can use a flight technique by operating a glider and using the air to provide thrust and lift. The sub-skills of airbending are flight and spiritual projection. Airbending is the element of freedom, and its season is autumn.
The only known Air Elemental is Finn Hudson.
Waterbending is a versatile element, it is unique in the sense that the original bender of the element was not an animal, but rather the moon. Similar to their element, waterbenders are extremely adaptable and versatile. Waterbending concentrates on the flow of energy and focuses less on strength and more on turning the opponent's own energy against them. While a bender's victory in battle depends on their skill or ingenuity, waterbenders, unlike other benders, gain a serious advantage or disadvantage depending on the amount of water around them, although highly skilled waterbenders can draw water from anywhere; they can draw humidity from the air and bend the water in living things, especially plants. As the element of change, waterbenders can fluidly and quickly alternate from defense to offense, from a wall of ice to a jet of water, turning their opponent's strength against them. The opposite of waterbending is firebending, with its relatively stagnant, direct philosophy. Due to its lunar sympathy, waterbending is stronger at night and ineffective during a lunar eclipse. However, to counter waterbending's ineffectiveness during a lunar eclipse, waterbenders gain immense power during the peak of the full moon. The sub-skills for waterbending are healing and bloodbending. Waterbending is the element of change, and its season is winter.
The only known Water Elemental is Liam Dunbar.
Earthbending demands a special connection with the earth that is achievable with neutral jing, listening, though seemingly doing nothing, and waiting for the right moment to strike. Like waterbenders, earthbenders gain an advantage or disadvantage in battle based on the amount of earth around them, though the conditions are not as extreme. Because of their element's stability and its stress on neutral jing, earthbenders stand their ground, absorbing or intercepting attacks until they completely overwhelm their opponents. Unlike the other bending arts, earthbending's strength equally lies in both offense and defense. Earthbending is in stark contrast to airbending as airbending's emphasis is on evasion and mobility while earthbending's emphasis is on fortitude and strength. The sub-skills for earthbending are seismic sense, metalbending, and lavabending. Earthbending is the element of substance, and its season is spring.
The only known Earth Elemental is Patrick Dunbar.
Firebending is the most aggressive bending art. Unlike other benders who depend on external sources of their elements to bend, firebenders can create fire using their internal heat source in addition to controlling already existent flames. As the element of power, firebenders have to be able to maintain a constant source of energy and balance in battle, unleashing a volley of direct, successive attacks. Firebending's relatively simple and direct style contrasts the complex and changing style of waterbending. Due to its solar affinity, firebending is stronger during the day and at its full power at noon, but completely ineffective during a solar eclipse. When a comet passes close to the planet, the power of a firebender is greatly increased. For a long time, disciplines of firebending were taught to be fueled by hatred, as opposed to the original source. Skilled firebenders are able to fly using powerful jets of flames. A notable feature of special firebenders is an ability to create a hotter, blue fire. The sub-skills for firebending are combustionbending, generating and redirecting lightning. Firebending is the element of power, and its season is summer.
The only known Fire Elemental is Brody Hudson.
