I am sure this has been talked about before at some point, at sometime, at someplace in the known universe that is this forum. But if not, have you ever thought about the idea of a Lost Chapters series? The episodes could consist of some side stories that where either not fleshed out enough or things that happened but where never seen but relevant to the story? The way I see it, it could be based between the 100 years the Avatar was missing, and maybe some side stories from the current time in the show. The reason I came up with the name Lost Chapters is because the series is book based, and as we know old books over the ages loose text and parts due to many reasons. I think it would be a neat idea if the creators of the show did something like this. Once the third season was over that is. If they did make something like this what stories would you like to see? I personally would like to see more of Irohs Ba Sing Se siege, and maybe some story in that abandoned earth kingdom city.
