Late at night, in one of the houses located in the center of the city, a window remained lit. It was a modest but cozy building, with pale stone walls and a roof of red tiles.
Inside, candlelight cast dancing shadows on the walls. Aang sat on the edge of the bed, his torso bare and his back turned to Katara. The skin of his back was a map of purple bruises and superficial cuts, and one of his shoulders jutted out at a slightly unnatural angle.
Katara stood behind him, her waterskin open beside her. Her hands moved with precision, tracing smooth circles in the air. Water flowed from her fingers, enveloping Aang's dislocated shoulder and emitting a faint bluish glow that illuminated the young woman's concentrated features.
—Take a deep breath and exhale —she murmured, her eyes fixed on the wound.
Aang obeyed. The water seeped beneath his skin, seeking out damaged tissues, and he felt the familiar warm tingle of healing.
—I've heard the Renegades are growing in number —Katara said, her voice low but laden with concern—. But they've never dared to make a move as big as attacking the Avatar before.
The Renegades. A faction of close-quarters fighters, men and women belonging to the lowest class of society—those born without the ability to bend. Marginalized, forgotten, pushed aside by a world that considered them inferior. Over time, that resentment united them, forming an organization of hundreds of formidable warriors who compensated for their lack of powers with fierce martial discipline and a deep hatred toward benders.
—You're right —Aang nodded, his jaw tight—. They were incredible fighters. Even without bending...
—Aaargh!
A cry of pain escaped his lips when Katara, with a firm movement, reset his dislocated shoulder. The bone returned to its place with a dull click, and Aang bit his lip, squeezing his eyes shut.
—Oops! —Katara said, but the glint in her eyes belied the innocence of her tone—. That was an accident.
Aang turned his head and looked at her with a raised eyebrow.
—Heh! Be honest. You're enjoying this.
—Aang, this is serious. Whatever that map they took is... if they were willing to kill the Avatar to get it, what else are they willing to do?
Aang's smile faded. He looked away toward the window, beyond the glass, where stars twinkled in the clear sky.
—I don't know.
His voice sounded darker.
Katara's fingers rested gently on his now-healed shoulder, and the water returned to the waterskin with a soft murmur.
—I'm worried about you —she said, her tone now softer—. You spend more and more time at the Air Temple. Alone.
Aang lowered his head.
—That's how... —he paused, searching for the words—. That's how I hold on to my past.
Katara walked around the bed and knelt before him, seeking his eyes.
—I know how hard this is for you.
Aang sighed deeply.
—When they attacked me, all I could think was that this might be the end. I'm the last airbender. If I die, my culture dies with me.
Katara reached out and took his hand, intertwining her fingers with his tightly.
—Aang. You may be the last airbender, but you are not alone. None of this could have existed without you. You made the rise of this city possible with your heart and your mind.
She looked at him with warm eyes and stroked his cheek with her thumb.
—Because of you, all nations live together in harmony.
Aang still wore a somber expression. Katara noticed and decided to change tactics.
—Besides —she added, a smile tugging at the corner of her lips—, you can't say you're the last airbender anymore. Though I really can't believe that boy literally fell from the sky. He reminds me of a certain kid trapped in an iceberg.
Aang's face lit up slightly, as if a small flame had ignited inside him.
—Yes, you're right. That boy appeared at a time when my heart was at its darkest. Giving me hope.
—With that boy inheriting your tribe's teachings, you'll be able to slowly revitalize the Air Nomads —Katara laughed softly, giving him a light tap on the chest—. But you really have a terrible sense for names. How could you give such a cute child such a fierce name?
Aang scratched his cheek.
—Well, I...
—I'm not letting you name our future children.
Aang choked on his own saliva. Katara let out a melodious laugh, and the sound filled the room like a gust of fresh air. The monk rubbed the back of his neck, embarrassment tinting his ears red, but a genuine, wide, carefree smile had finally replaced the shadow that had previously darkened his face.
Gradually, Katara's laughter faded, and Aang's smile faded as well, replaced by solemnity.
—Anyway... —his eyes regained their sharp edge of determination—. Whoever that person is, Sonum, I need to find out more.
Katara nodded, her own expression turning grave.
—Whatever it is, we'll find out together.

The room Katara had assigned to Noah was modest: a low bed with linen sheets, a light-wood desk by the window, and a hand-woven rug that muffled footsteps. Moonlight filtered through the half-open shutters, drawing silver lines across the stone floor.
Noah sat in the center of the rug with his legs crossed and his hands resting on his knees, palms facing up. His eyes remained closed as his breathing flowed in a slow, steady rhythm. His mind, however, worked at full speed, dismantling and reconstructing every piece of information he had absorbed over the past few days.
Bending was an art that at first glance seemed simple: moving water, earth, fire, or air with martial gestures. But beneath that surface lay a complexity that would have escaped any observer who did not possess his analytical ability.
Bending was the art of subduing the elements to the master's will using the vital energy flowing through the body. That was the extent of the basic definition known to the people of this world. But in Noah's eyes, something deeper was hidden in this art.
If bending consisted merely of using vital energy to directly manipulate matter, the energy expenditure would be so brutally inefficient that all benders would have abnormally short lives as a consequence. Furthermore, if that were the case, any bender could use any element without restriction, and that did not happen.
The reality was that each bender's life force was synchronized with a specific element.
It worked like a resonance between the bender's chi and the elemental particles of a particular type. Using that affiliated life force, a bender could control the elemental particles present in the environment—in the air, in the earth, in the water—but they always needed those particles to already be there. They could not create them from nothing. A firebender did not generate fire; they manipulated the igneous particles suspended in the atmosphere, concentrated them, excited them, and turned them into flames. A waterbender did not create water; they shaped what already existed naturally in the water around them. They were artists who painted with pre-mixed pigments, not alchemists capable of manufacturing their own colors.
In contrast, a Magus operated in a radically different way. A Magus used their spiritual power to gather scattered elemental particles and shape them through a predefined spell model, creating an effect from scratch even in an environment where those particles were scarce. But that advantage came with a limitation: once the spell was cast, it became something rigid, like a fired arrow. The caster no longer had control over it. At most, they could forcibly dispel it, but at the cost of suffering a violent backlash from the energy rebound.
