Avatar: Legend of Grace

(Based in 2020)
They taught us about the hundred year war in history, but it never seemed real to either me or Erity. Her and I thought in the same ways.
I loved her. She felt like a dream I was forced to wake up from when she left to master the 4 elements.
Everyone else started to see her that same way too: too wonderful to be true. She was fierce and fearless like fire, peaceful like air, gracious like water. And she was born an earth bender so she was grounded, determined and strong. And I wanted nothing more than to love her alone. Threats of war and opposition rose but like magic Erity made them dissapear.
She was only 19 when the world experienced a different kind of peace, a hopeful, beautiful kind that made the hundred year war feel like a well-constructed lie.
But all things can be broken. And the Avatar was prepared to fight every battle, except for one.

A young air bender from the North was the first to be infected. They say she wouldn't stop bleeding out of, well, everything. The pathologists said they found acid and pieces of organ tissue dissolved in her blood and her black vomit. It was like the disease was trying to turn her inside out. The healers and the doctors tried every method, every drug, but her body would not stop rejecting itself.
Her father euthanized her. He said she looked empty and that her eyes already looked dead.
The disease spread and millions died slow, painful deaths.

Then, one cold night in November, every single screen turned black. And a message was broadcasted across the whole world.

"You will comply. You will no longer bend or fight. You will no longer live for yourselves, but for us. The Avatar cannot protect you anymore. Resist and you will not be given the cure. Resist and more of you will die. You cannot win, for you have already lost.
~ The Fifth Element."
