Ten years later.....
Zelda and Seto were married and had two children; a son, Zeka and a daughter, Mika. Zelda turned out to be the best firebender everyone has ever seen and passed it down to her son. Seto taught Mika how to become a powerful warrior just like him.
TJ married a girl with light brown hair and brown eyes. He had a daughter named Lin. He taught her how to fight like him. He looks exactly like his father, Zuko.
Andrea passed away from a disease called Leukemia after Zeka was born. Zuko still lived to watch his grandchildren fight like his children. Ozai passed away after Lin was born. Azula taught Zeka, Mika, and Lin how to firebend since she's still a firebending prodigy. They got really good at it, mostly Zeka.
Those Seven years have been very peaceful since the war has ended.
The End!
