This is an illustration from a fanfiction I'm writing called "Broken Dragon." Basically, it follows the story of Azula, Mai and Ty Lee post-Sozin's Comet. Azula is insane and locked up in prison. She has these violent fits every now and then, at which point she's chained down on the floor of a cage and muzzled so she can't hurt herself, or anyone else. Azula is so chained in this pic, and Ty Lee's trying to comfort her - in a nutshell. (There's more to it than that, but I'm not going to transcribe an entire chapter of the story here! :P ) Ty Lee and Azula are from Avatar:The Last Airbender.
