Avatar The tale of two

Fire... Air... Water... Earth.

For all that is good in this world, evil shall always exist alongside it.
T'is a natural law for one cannot exist without the other.
Love cannot exist without hate. A victor can't exist without the vanquished. Peace can't exist without conflict and war.
So to as light cannot exist without darkness.
We know that the light shines in the darkness and the darkness did not overcome it.
But did we pause to think what surrounds that light?
Yes, it is darkness itself.
The light may be strong but it will never be strong enough to completely extinguish the darkness around it.
Even if it did, it will reappear. For what is light without darkness?
Hence, most good that is perpetuated in this world has an ulterior motive.
Whether it's for money, fame, power... Time will tell.
But, when the darkness started to grow within the light and tint its pure, white rays black—
The people mistook it for the same light they'd always known.
Blinded and weakened by situations such as peace, comfort, lofty dreams and foolish ambitions, they did not see their error.
A darklight.
When the true light did come, they did not recognize it nor did they accept it.
The Avatar has returned, now a member of the earth-kingdom, but is he the one the whole world knows and remembers?
The bridge between spirits and humans?
The one who brings balance to the world?
The master of all four elements?
Or, the harbinger of the dark age?
