2012

The fire nation government is corrupt, all water benders are illegal. A water bender girl and her non bender brother find a boy, half dead and decide to look after him. When he gains consciousness, he repeals himself to be an air bender, not just any air bender, the last one and also the avatar. Toph is the daughter of fire lord nobels who worship him, also nobody knows she's an earth bender and believe she's a non bender. Zuko instead of being banished he's sentenced death for speaking back to his dad and is a runaway. Katara doesn't trust him( obviously) Suki is part of a group of people who are against the fire nation. Sokka is just Sokka, providing a glimpse of light when times are dark.
