Energy Saga takes place after the end of the television series. It's about Aang fulfilling his duties as Avatar and rebuilding the world which has been devastated by a hundred years of war. In order to help make the world he lives in now more like the one he grew up in, he starts learning energybending, one of the capabilities which the Avatar Spirit has; however very few incarnations of the Avatar have ever used it. Without the instruction of his past lives, he's essentially on his own. However, as he discovers what energybending is capable of, he learns that all of his actions have consequences. The series begins at the end of Avatar: The Last Airbender, but some darker themes become introduced as it goes along and it becomes more PG-13 than the canon show.
Aang - The Avatar and the protagonist of Energy Saga, Aang, resides in the South Pole with his family and travels frequently to the Southern Air Temple. During the series, Aang gradually becomes more powerful and knowledgeable in energybending.
Katara - The waterbending wife of Aang, Katara lives at the South Pole and shares in Aang's adventures after the Hundred Years' War.
Zuko - Fire Lord, Zuko does the best he can to get his country back on the right path, encountering trouble along the way. Some of his countrymen were not satisfied with the outcome of the War when Zuko took over.
Sokka - Sokka, Katara's brother and Aang's brother-in-law, is now Chief of the Southern Water Tribe. Ever-loyal to his friends and family, Sokka joins Aang and Zuko on their respective journeys.
Toph - Toph was named the Queen of Omashu after Bumi passed away and remains one of the greatest, if not the greatest, earthbenders in the world. With her in charge, Omashu remains a safe haven Team Avatar can count on no matter what happens.
Migo - Migo is a new addition to the gang. He is a talented earthbender, though not as talented as Toph. His laid-back, easy-going personality stands in sharp contrast to Toph's sharp, confrontational, tomboyish one. He is generally friendly to anyone he meets and tries to help out when someone is in trouble.
Trinley - Like Migo, Trinley is a new character in Energy Saga.
Tenzin - The first son of Katara and Aang, Tenzin is an airbending prodigy who learns from his father at the Southern Air Temple.
Kaddo - The second son of Katara and Aang, Kaddo is a waterbender who learns from his mother at the South Pole.
Vameira - The youngest child and only daughter of Katara and Aang, Vameira is an airbender who learns from her father at the Southern Air Temple.
Neinei - The daughter of Mai and Zuko, Neinei is Princess of the Fire Nation and an aspiring firebender.
Hinko - The son of Suki and Sokka, Hinko is an aspiring warrior who lives at the South Pole.
"Energy Saga is the best fanon I've ever saw. I am not lying now, but it is the best story I've ever read. No relation to Avatar. AvatarRokusGhost : Write stories, publish books, win money."

"This series does what no other does and takes you into the mysteries of Energybending and gives it so much more than just taking away or giving bending abilities. Its plot twists are amazing and its character development....oh my."

"My grudge on "After the War" fanons is slowly but surely fading because of this. If you haven't read this, you don't know fanon universe. Great job."
— BlackMonkey, author of The Avatar Rhythm in his review
"Excellent, excellent chapter. The culture clash, the pains of adapting to a new family, the careful management of the energybending theme, were all outstanding and quite worthy of praise. This is a GOOD fanon."
