The great thing though about inventing your own fictional world is you get to set what ways your characters follow. So what are the ways of your world then? Why have they become the ways most will follow? Who rebels against them and why? What is the punishment for those who don't follow the ways of your world?
Did your world invent their ways or are they in turn influenced by other alien species they have had contact with in the past? Does your world watch what other planets' peoples are doing and copying ideas they like the look of? (If so you can bet copyright infringement is almost certainly not a big issue here!).
What are the ways everyone must follow if they want to live? Who enforces these and how?
Plenty of possible story ideas there... happy writing!
