Prologue
These paragraphs are meant to give you a little better understanding of where everyone is, before you start reading the story. Please note this is only a basic summary of each character and doesn't mean they will remain this way throughout the whole story.
Avatar (Aang)
After the war has ended the Avatar returned with Katara to help rebuild the Southern Water Tribe to its former glory, but soon afterwards he realized that his feelings for Katara where more like that of a brother's love towards a sister. Eventually the Avatar left Katara and the tribe to head north. At this point Aang is now a fully realized avatar and has adopted the Northern Water Tribe as his new home and has also started a family, with his wife Aven, a healer and a beautiful five-year-old daughter named Tara.
Katara
When Aang left the Southern Water Tribe, her heart was broken since though Aang only loved her like a sister she loved him more than he could imagine. Eventually she forced herself to move on, but even now, every once in a while, when she sees Aang hold Aven she quietly wishes it was her in his arms instead. She is still living in the South Pole and has become a much better waterbender and after Master Pakku expected the position of Chief of the Southern Water Tribe she became in charge of training benders for the tribe.
Sokka
As everyone expect shortly after the war Sokka purposed to Suki. Their life on Kyosh Island has been quite nice, and they have been blessed with two find boys, Kan age seven and Hun age five. During the years Sokka had moved to be more of an inventor than the warrior he always wanted to be, though he is still considered a master swordsman. Sokka with the help with Toe have created a nice size laboratory for their experiments and inventions, which Suki has mentions many time: "end up blowing up in the two inventors' faces."
Toph
Toph was happy to return home since now her parents finally had excepted the fact that their daughter was not as helpless as they once thought, though how could her parents argue when the new Fire Lord (Zuko) had praised her as a great hero and one of the most influential people for ending the war. Like Katara she has decided that after the war she would uses her skills to help train new earth benders, some of which have also become metal benders.
Zuko
With his father defeated Zuko took the thrown but unlike his father he was a just ruler, who has tried hard to regain the respect of the other nations which had been lost by the years of war. He still at times is not the most pleasant person to be around, when it came to most people, but yet he had grown much since the war ended, through guidance from his uncle who eventually returned to Fire Nation to stands by his side; now as Zuko's royal adviser.
