Disclaimer: While this does take place many years after The Legend of Korra and I did come up with many of the characters on my own, the world is not mine and the characters are influenced by the previous series. I'm playing in the Avatar sandbox quite liberally here, but I still do not own it.
It was 91 years before the birth of Avatar Zhong that I lost the connection to my past lives. It was one of many hardships I struggled with as a teenager, but eventually I knew that the cycle must go on, and I became at peace with it. The world was changing, and Korra would be synonymous with "new" and "modern". I always thought it would be Aang that would be remembered by the future, but it was my face that was plastered all over the world for generations to come. The joys of being born in a world of photography and movers I guess.
I can't say that my life ran smoothly after my talk with Kuvira. There was a lot that needed to be smoothed out between humans and spirits in order for us to live harmoniously. That's how I spent the rest of my life. I stopped some civil disputes and I helped spirits and humans understand each other better. But mostly I just spent time with my family.
The kids grew up, and eventually moved out. We were together, then we were apart, and eventually our family grew even more. Asami and I treasured our grandkids when we had the chance to see them, but the empty nest hit us hard. Technology was advancing and it was an exciting distraction for some time. Eventually though, I found myself living entirely alone. After that, even technology couldn't distract me anymore.
I knew it was time for me to move on.
But this story isn't the legend of Avatar Korra. This is the legend of Zhong, and the legend of Heiwa. It's the legend of Platicorp and Yoa Computers. After me there were two avatars that found themselves fighting the same foe, even if they were born in different times. Two avatars who could only look back as far as me and think...
What came before Korra?
