The world was once kept in balance by four nations: the Water Tribe, the Earth Kingdom, the Fire Nation, and the Air Nomads.
The sole being entrusted with maintaining that balance was the Avatar—the one who could wield all four elements: water, earth, fire, and air.

But when the Avatar suddenly vanished, the Fire Nation began a war, plunging the world into chaos.

One hundred years later, a girl of the Water Tribe named Katara and her brother Sokka awaken a boy who had been sleeping within an iceberg.
He is none other than the legendary Avatar himself—Aang.

Aang
A boy chosen as the Avatar one hundred years ago, and the hero of this story.
Overwhelmed by the immense responsibility of being the Avatar, he ran away—and was trapped in suspended animation within an iceberg.

At heart, Aang possesses a strong sense of justice. After awakening, he stands alongside his companions to confront the Fire Nation.

He primarily fights using Airbending, but over the course of his journey, he learns to master Waterbending, Earthbending, and Firebending as well.

Katara
A girl of the Water Tribe, passionate and compassionate, and the emotional anchor of the group.

She lost her mother in the war against the Fire Nation, carrying a quiet but powerful anger toward the conflict.

A prodigy of Waterbending, Katara becomes Aang’s most trusted ally during their travels—a steadfast partner who understands and supports him.

Sokka
A young man of the Water Tribe and Katara’s older brother.
Though sarcastic and often joking, he is sharp-witted and supports the group as a tactician and strategist.

His admiration for his father, along with his strong sense of duty and pride in protecting his tribe, sets him apart.

Though he cannot bend the elements, Sokka brings laughter, ingenuity, and morale to the journey.

Toph Beifong
The daughter of a noble family from the Earth Kingdom.
Blind since birth, she “sees” the world by sensing vibrations through the ground.

Chafing under the suffocating protection of her parents, she leaves home in search of true freedom.

An exceptional Earthbender, Toph joins the journey in order to teach Aang the ways of Earthbending.

Zuko
A prince of the Fire Nation who was banished after defying his father, Fire Lord Ozai, and left scarred both physically and emotionally.

Tasked with capturing the Avatar to restore his honor, Zuko travels the world in pursuit of Aang. Over time, he begins to question his destiny—and ultimately chooses his own path, becoming Aang’s ally.

A master of Firebending, Zuko teaches Aang the art of fire and fights alongside him as a trusted companion.

■ Airbend
Airbend is an ability that allows you to temporarily exile a permanent.
A permanent exiled this way may be cast by its owner by paying {2} instead of its original mana cost.

This can be used to temporarily remove an opponent’s threat, or to reuse your own permanents’ enter-the-battlefield abilities.

■ Waterbend
Waterbend is a type of cost, most commonly required for activated abilities or additional costs.

If an effect instructs you to “Waterbend 5,” you must pay a total of five mana.
However, this cost may be paid not only with mana, but also by tapping artifacts and/or creatures you control.

■ Earthbend
Earthbend is an ability that turns lands into creatures.

For example, “Earthbend 2” causes one land you control to become a 0/0 creature with haste, then puts two +1/+1 counters on it.

If a land that became a creature this way would die or be exiled, it instead returns to the battlefield tapped under its owner’s control as a land.

■ Firebending
Firebending is an ability that allows a creature to add red mana when it attacks.
Mana produced this way doesn’t empty as steps and phases end, and remains until the end of combat.

A creature with “Firebending 2”, for example, add {R}{R} when it attacks.
