Description

"Water.
Earth.
Fire.
Air.

In the the old days, there was a time of peace when the Avatar kept balance between the Water Tribes, Earth Kingdom, Fire Nation, and Air Nomads. But that all changed when the Fire Nation attacked. Only the Avatar mastered all four elements. Only he could stop the ruthless firebenders. But when the world needed him most, he vanished. A hundred years have passed and the Fire Nation is nearing victory in the War. Two years ago, my father and the men of my tribe (Southern Water Tribe) journeyed to the Earth Kingdom to help fight against the Fire Nation, leaving me and my brother to look after our tribe. Some people believe that the Avatar was never reborn into the Air Nomads, and that the cycle is broken. But I haven't lost hope. I still believe that somehow, the Avatar will return to save the world."
-Katara (episode 1 opening of the Last Airbender)

Well, the avatar has been found. Upon hearing the news, the southern and northern water tribe along with the earth kingdom decided to do a final rebellion to stop the fire nation and end the century long war. The avatar is joining in the fight but he needs some time to master all 4 elements. Hold out and have the avatar guide you and your forces to victory. However, with Sozin's Comet in the atmosphere, the Fire Nation is at its peak.

PS: You play as the earth nation in this scenario.
