There used to be a java game on nick.com for avatar: the last airbender. Basically you create your own element bender of your choosing and walk around different stages with challenging enemies you gotta fend off with your bending. I last played this around 5-6 years ago on nick.com, but that game is no longer there. Anyone know what I mean and/or know if it's still around the web?Update:Actually the game I was looking for was a single player campaign only. However this multiplayer one isn't bad..

The only one I can think of is called Avatar: Autumn Twilight. You could be an earthbender or waterbender and you had to play through a storyline with 3 chapters. It matches the times you are talking about. I don't know why they removed it but they did and I don't think it's online anymore.Sorry but hope this helps.
