Okay this is just a game where the first person tells part of a story, the second person continues it and so on. This will be based on what happens after a certain episode. (for example if it was between the headband and the painted lady, we could call it Book 3 Chapter 2.5; if it was after the season 1 finale, we could call it Book 1 Chapter 21) Stories may be ended by anyone. The next person will start the new story.

There are two types of stories:
Script: Each person writes up to 5 lines said by the characters or scene descriptions.
Event: Each person writes a event that happens to the Gaang.
When you start a story, you specify the type of story, the book and chapter name. You do not start writing the story. Basically, you set the scene, they tell the story. You can post as much as you want, but never twice in a row.

I'll start the first story:
Type: Event

Book 1 Chapter 21 (no toph, azula is allowed)
