I’ve mentioned it before, but it’s recently completed and hence bears bringing up again:
Embers, an Avatar: The Last Airbender fanfiction, is one of the best works I’ve read, fanfic or otherwise. At 750k words, it’ll keep you entertained for a while. It features characters who are generally smart (at least some of them, and in ways generally more age- and culturally-appropriate than eg HJPEV) and significant fleshing out of the world, with the latter drawing heavily on the author’s sometimes-cited research: see eg the author’s notes at the end of chapter 30 (warning, slight spoilers, though nothing that will make sense out of context) or at the end of chapter 47 (somewhat more significant spoilers).
You don’t need to have seen the show to know what’s going on, but it’ll help, and the show is worth a quick watch if you’ve got time on your hands anyway. Don’t skip this work just because you don’t have time for the show right now, though. Also, there’s a prequel of sorts called “Theft Absolute”, which is three orders of magnitude shorter and will not make much sense without the show; it’s not necessary for Embers.
I enjoyed ember for 20 or so chapters while it did a great job of developing characters and justifying oddities about the fire nation in canon with new effects on bending and had a great novel perspective on Aang but then it really went off the rails in terms of adding too much non-avatar universe content.
