Epilogue:
Ellie lay in bed. It had been fifty-eight years since the end of the Hundred Year War. Already, Aang was gone. She believed that the White Lotus was still searching for his successor. Aang and Katara had married and had three wonderful children. One a nonbender, one a waterbender, and one an airbender. Ellie knew that Aang had been ecstatic with the birth of the airbender, but she also knew that he cherished all of them.
Much as she cherished her own children. She had gone on to marry Zuko not too long after they were both of age—in Ellie's mind, at least, which was when she was nineteen and he was twenty-one. Most Fire Nation citizens—especially the Fire Lord—married by the time they were seventeen. Seven years later, they had a set of triplets, two boys and one girl, and an additional girl a few years later. All of them were firebenders.
The oldest was a boy, Colton, and he was next in line for the throne. Ellie had always had a soft spot for him, as he was the only of her four children that sported her blonde hair. She was glad that the gene had passed down at all, knowing it was a recessive trait. But, she also doted on Yukin, who was a sweet, kind-hearted child. In personality, he reminded her of Zuko.
Already, she had seen the birth of five grandchildren as well. Two from Colton; one from Yukin; one from the youngest, Raina; and even two great-grandchildren from Yukin's daughter, Ursa. They were all bright and cheerful. The oldest was Colton's eldest son, age twenty-five, and the youngest was Yukin's latest granddaughter, who was five.
Currently, Ellie knew that her husband was out of the house. Something urgent had come up, though he wouldn't tell her what it was. She couldn't come along, because she had been getting weaker the past year, and he likely didn't want to worry her. Of course, Ellie was more jealous than worried, so perhaps that wasn't needed.
Zuko also left Yukin, the old mother hen, in charge of watching her.
But Ellie could feel that she wouldn't last much longer.
"Yukin," she said quietly, her voice cracked slightly with age.
"Mother?" he asked, coming to her side and clasping her hand.
"I need you to leave me for a second."
"What? Why?"
"Just trust me," Ellie whispered. "I need to be alone."
The boy—well, older man—walked towards the door, occasionally giving her a hesitant glance, before exiting. Once the door close fully, Ellie closed her eyes in relief. When she opened them again the time spirit, stood before her.
"I need one last favor, old friend," she said softly.
And she knew she didn't even have to tell him, because he was looking at her with those knowing eyes, holding a hand out to her in invitation.
Now, if you want more, you can go and read the sequel. I have just posted it. It's a Legend of Korra story, called The Other Avatar: Darkness Reborn.
