This is my view on what would have happened if the 4th book was actually made, minus a few tweaks to make it fit with the Legend of Korra. I took Aaron Ehasz' plot that he posted recently and edited it, taking out the Zutara plot and changing things round. It is rated T due to more heavier violence and injuries. Any suggestions and reviews will be greatly appreciated.

What if Tom and Jake Sully had another identical sibling? What if Tom never died? Lenna Emersyn Sully is a wild and spirited person and was the only girl of the three children. Living her life away from family ties and into the world of work, opportunity knocks at her door when her triplet brother, Tom, invites her to go to Pandora with him and Jake.

There are no Guardians, not anymore. The war with the Darkness is over, and there is no longer a need for them; now there are Keepers, echoes of what had once been Warlocks and Titans, who maintain relative peace in spite of infighting. Hunters have disappeared, no longer permitted to explore the wilds. Yet, myths of a true Guardian who still lives persist; the Last Hunter.

I'm different. I'm strange. I do not belong but when I go to Pandora to help my mother, I feel like I'm coming home for the first time. When I arrive, things start to happen and I feel connected to this place some how. I need to figure this out. I need to know why I feel what I feel. I need to know who I really am.

Set straight after the movie finishes. Jake and Neytiri are happy until an old familiar threat is set to return while their lives are about to be turned upside-down by an unexpected blessing.
