Korra sat in her family home, her eyes falling on a photograph of someone who looked strikingly like her. Her curiosity piqued, she turned to her parents. “Who’s this?” she asked.

Senna exchanged a look with Tonraq before speaking softly, “He’s your brother.”

“My brother?” she repeated, her voice barely a whisper, disbelief evident in every syllable. Her eyes drifted to the figure in the photo—Aoki, her brother?—standing there with an unsettling calmness, his detached gaze fixed on her. “How could I have a brother and never know?”

Senna’s hand quivered as she placed it on Korra’s shoulder, her face etched with a sorrow and guilt Korra had never seen before. “Korra, you were too young to remember. Aoki... he was different. From the moment he was born, the spirits marked him in a way we didn’t understand. Before he could even walk, he was bending both water and earth effortlessly. At first, we thought it was a blessing.”

Tonraq’s expression darkened, his jaw tightening as he glanced at Aoki. “But as he grew, his abilities became… unsettling. He could shift between elements at will, even though he wasn’t the Avatar. It wasn’t just bending; he was altering the very essence of the elements, manipulating them in ways that defied logic.”

Korra’s mind raced, her thoughts spiraling in a whirlwind of confusion, anger, and fear. “Why didn’t you tell me?” she demanded, stepping back from her mother’s touch. “How could you keep something like this from me? My own brother?”

Senna’s voice trembled with emotion as she explained, “We had no choice. When Aoki was six, he… vanished into the spirit world. He was gone for days, and we feared the worst. When he returned…” Her words faltered as she shared a glance with Tonraq, both of them visibly shaken.

Tonraq picked up where she left off, his tone grim. “When he came back, he was… different. He spoke of spirits, of powers beyond our world. His presence felt darker, more dangerous. His control over the elements had become erratic—unpredictable.”
