Can you answer questions about the world and characters you’ve created? Can you imagine them living on after the novel/short story you’ve written? Do they seem as real to you as the real world out there? No. It’s not a sign of insanity but a sign you’ve thought your world out properly.
Does your society have rules? The answer should be yes. Even a society seemingly based on anarchy will have someone in control of it all. Do your rules work? What happens when these are broken?
How are your characters’ basic needs met?
What is the hierarchy (and there has to be at least one, someone has to be top dog)?
How is your world governed? Are there rules nobody can break? What are the reasons?
In dealing with magic, can everybody produce the same amount? Or do certain groups have more magic than others? Can those lower down the scale “earn” or “learn” more magic to bring them closer to their superiors?
What happens if someone defies the basic rules or some lowly herbert betters themselves magically so they become superior? What would the fall out be?
What happens if someone from the superior class magically speaking rebels against that or the structures of your society?
