I don't know much about the tags or rules in Meta, since I usually just briefly lurk, so I'd appreciate it if someone can fix the tags to be more appropriate and I apologise if I've broken any rules here.
I'm asking about my question is there other possible fuel for fire other than common oil/fuel?, as it was closed as off-topic and there was no explanation whatsoever of why it was considered off-topic in the comments, so maybe I'm missing something?
Since my question basically asks about any unique, exotic or uncommon fuels for lighting fires, with the criteria mentioned in the question
About the duel inspection, it is to explain what it is, when it happens, and how it works. And as for the duel itself, it is to explain what the fire alternative is used for so I can get a clearer answer.
If it's considered story-based, I personally don't see it that way, so I'm kinda confused. Usually, before a question gets closed, someone will mention the flaw in the comments.
So is my question really not about worldbuilding?
