All the regions had come together for the first time in 100 years. The Earth Kingdom, The Fire Nation, The Water Tribes, you name it. Why? The world... is ending.
Expectedly, Team Avatar (or the Gaang) were at the front of this fight for survival, though of course there were other people. Almost every civilian in any and every region that could fight would contribute. Well, albeit, they kind of had to. The world is ending, and so you'd need everything you could get.
Nobody knew why, who, or where it came. It was a mystery. But everyone needed to work together if they wanted to stay standing. Aliens, monsters even had invaded the lands.
Disagreements rose, to be expected. But surprisingly, even the most power-driven ( Fire Lord Ozai, we're looking at you ) were impressively rational. Not really that much, but still somewhat aware of the real concerns.
Aang: He glanced around at everyone. It's like his dream had temporarily come true, the regions working together. "Wow." He mumbled, smiling lightly.
There were a few people sharpening their weapons, like Sokka, for example. Some were practicing their elements and training, such as Katara and Zuko. Others were trying to deceive strategies. Overall, it is a friendly but serious environment.
Sokka: "..." For once, he's silent, though obviously that won't last for long.
Azula: She practiced her lightning bending in a secluded corner, a few grunts escaping her mouth here and there.
Katara: Katara calmly sat at a lake, practicing her water bending. She was getting better and was proud of herself for it!
Zuko: He was also practicing his element, Fire bending. He made sure not to hurt anyone, shooting most attacks into a clear area of the forest everyone was in so that it wouldn't hit anything.
Toph: She laid back, resting with her feet on still on the ground. She hummed.
The world is literally on the verge of ending, so obviously, you're doing something too. What is it? Practicing? Devising a plan? Training?
