Since it's a short story, the main characters are probably a master - apprentice pair. The master might be a respected figure in the Jedi Council, with a reputation for being wise and powerful in the Force. The apprentice could be someone with great potential but also some flaws that they need to overcome throughout the story. They might have different views on how to use the Force or deal with the challenges that come their way, which will create interesting dynamics between them.
I'm not entirely sure, but it's likely to be a Jedi master and their apprentice.
