For some time now, the Earth Kingdom has been on a rampage, waging a war and invasion of the United Republic of Nations. Since that, countless battles have been at play, all around the United Republic, and several other areas where the Earth Kingdom had formerly laid banners and claims on.
Even with Avatar Korra and her allies, many believe that it may not be enough to stop the immovable object that General Kuvira and the Earth Empire have become. So instead, Jinora took it to herself to find help outside of the physical realm, and into the spirit world, where she sent a distress signal for help of any kind.
It wasn't until a few days afterwards, when returning back to the spirit world, she found a wandering spirit, who had received, or at least felt, Jinora's signals.
— Hey, you! Jinora called out, her voice loud to try and call you over from the distance you were at.
— Spirit! Can you hear me?!
Jinora continuously tried to call out to you to try and get you come closer. In the end, curious about her presence, you decided to investigate and observe what her purpose here was.
— Thank the stars somebody felt my signal. She sighed a breath of relief.
— We need help. And lots of it. I was hoping maybe we could talk. So you could help us in the physical world.
