Crack.

I felt the wrenching sensation, his darkness coming between us as we were ripped apart.

Crack.

There is no torture that compares to the pain of that separation. For the first time in millennia, we were no longer one.

Crack.

Shadowy tendrils whipped against my weakened form. I could only whimper feebly as I began to lose you, lash by lash, lifetime by lifetime.

Crack.

First Aang, then Roku and Kyoshi. Then Kuruk and Yangchen. Each incarnation disappeared in succession, snuffed out like so many candles in the wind.

Crack.

Their memories vanished with them, and even their names fled my memory.

Crack.

Finally, only one remained.

Crack.

Wan. Oh, my dear friend. I had hoped that the day would never come, but a part of me had always known we would not be bonded forever, after all. Very little is this existence is eternal. Even Vaatu and I will eventually cease to be in countless eternities to come. I suppose it only follows that our union would too be shattered by the currents of time.

Crack.

It hurts to bid you farewell. At least in this state of being - our combined Avatar spirit - I could maintain some connection to your spirit. We could be together through your lifetimes, and we never truly parted from one another.

Crack.

But now I fear- No, I know I will never be with you again. My ties to Korra are breaking even now.

Crack.

A spirit should never learn to regret. It is such a human trait, to long for what will never be and agonize over the unchangeable truth and past. At least humans may shed that poison at the end of their lives. Immortal spirits have no such luxury.

Crack.

I regret that your spirit must be put through this misery. I regret that you must continue to live on in a world turned dark. I regret that we will be never one again. I regret that our parting is so horrible and sudden, that I will not even remember you after this moment.

Crack.

Forgive me.

CRACK.

Good-bye, Wan…

CRACK!
