Info + Questions

So yeah, I'm conflicted about which I should go with. Mc is an Airbender that is monk Gyatso's age, or Aang's age, or mc was born by a hiding Airbender during the 100-year war.

Feel free to bring any suggestions on what I can do with an Airbending story or any changes I could make to the og story in this chapter so I have more ideas.

Btw I'm thinking of continuing this story to the end of Korra so ill be doing both shows.

Laid-back mc that observes and explores more, or make the mc interfere in everything in the story?

Chapter size? 1000 words or larger chapters? Shorter chapters would allow the story to reach a bigger audience.

What are the best sub-bending elements?
