Here is where you could just create your own Avatar scenes to share with other people. Similar to writing fanfiction. You may choose to write a scene together or by yourself for others to read. It could be silly or serious, anything you want it to be. Below is mine, just so you may get an example.
Zuko: I knew there is good in you my sister. Aang: Yeah. Azula: It is to late for me my brother. The two pulls out two red lightsabers and begins to duel. Ozai: Good.
