Azula brings her allies back. She is powerful, and she is going to rule the world. No foolish Earth Kingdom peasant will stand in her way. Neither will Ty Lee's frivolous circus or Mai's pathetic younger brother, and most certainly not the Avatar.

or: the rise and fall of the fire nation princess azula.
