Prologue

Everything dies.

Two words that, if you said them to anybody, would agree with you with a sad smile and a simple shrug of the shoulders. The mind accepts this, but not the heart. Who would want to believe such a thing? No one.

But it is a harsh truth. Some say the truth sets you free.

They're wrong.

Lies protect us from the truth. They feed us, nurture us, and build up false walls and constructs that defend us from the unbearable reality of this world.

I once believed in a thing called hope. It is what drove me and the rest of my friends to end a terrible war that had lasted for over a hundred years. A tyrant was dethroned and a legend was born. The legend of the Avatar, who had been lost for over a hundred years.

Aang.

The twelve-year-old boy who had the amazing ability to bend all four elements. He was the spirit of the planet reincarnated, the hero that everybody needed at a time when the Great Balance was disrupted by the Fire Nation's all consuming conquest of the other kingdoms.

He stripped the Fire Lord of his mighty bending powers and rendered him useless. Ozai now rots in his cell, the rest of his life being spent pondering the atrocities he carried out during the war.

It was over. Destinies had been fulfilled, and the world was finally at peace.

But something went wrong.

And now we're on the run.

There's no one left.

The world is in peril once more.

And Aang is not here to save it.

I don't know how much longer I can do this. My hand's shaking just from writing all this down. I have to get a grip – he's depending on me.

Everything dies.

Even gods.

My name is Katara of the Water Tribe. This is a final testament in case this plan – this final, desperate, last-ditch effort – doesn't work.

Aang forgive me. Each word I write is a further damnation to my soul. To you, the one I love so much –

Prepare to die.

I know it's short, but I'm just throwing out an idea here. Read and review. More to come (hopefully soon).
