Hello, I'm kinda new here and I want to share my current FFIX fanfic. It deals with the simple premise that
Spoiler:
Garnet Til Alexandros XVII, the real one. Is alive, and lived the life of a street rat; a thief. When she finds out about her heritage, both as heir to Alexandria and as a summoner, she plots a plan to reclaim what is hers.


I would like to hear suggestions from writers here on how I could improve the story.

Also here are some of my questions:

1. If
Spoiler:
Garnet gets found out, Would Steiner or Beatrix betray Sarah?


2.
Spoiler:
In the game, it mentions that the real garnet died. But there was no mention about her corpse and anything about her. Can you give me a good scenario in which I can exploit; which can be the eventual reason why she is alive.
