We got a huge number of questions (200+), but wanted to narrow these down so that community could help me choose. I chose these questions based on how thoughtful and well-crafted they were. If any of these questions have been answered by show-runners in an interview or other fansites, PLEASE let me know so I can strike it from my list.
We'll narrow these down to about 10 questions (give or take) and I want to credit the question back to the user who asked!
1. Will the graphic novel series (in all three instalments, maybe) show the creation of the Republic City and the advanced technology that we see in Legend of Korra? - from Natsu11, Lovelyb0nes, NinjasandNavi, Shock Dragoon
2. Will we see the spread of the unique bending forms acquired in the series to the general public during Aang's lifetime or afterwards? - from H-Man Havoc
3. Will we get to see the status of the characters' romantic relationships beyond Aang and Katara's? - from Free as a Bison
4. What inspired you to write a graphic novel for Avatar; and will you be involved in the creative process past the novels? - from N 3rd Street

20. Will it show some relatives of characters in LoK? Like Bolin and Mako's grandparents? - from PreservationWings
21. *Will there be cameos from familiar characters? - from Free as a Bison
- If these questions are chosen, it might be a good idea to combine them and ask a more general question about cameos from familiar characters and throw some of the familiar ones in.
Thank you again for those who participated, and I'm so sorry if some of the questions weren't included; the goal is to narrow these awesome questions down.
