@JBH and the OP also didn't say "I want to set a story in this 3rd party universe". But that's what you were assuming with your "a)".

@JBH the only difference is that I assumed good faith and you assumed bad faith.

@datacube I made no such assumption. The OP didn't say "I want to set a story in this 3rd party universe." But the OP also did not say, "Here is a 3rd party universe and I don't want a solution based in it." The OP also did not say, *here's something interesting from a 3rd party universe and here are the constraints from my universe, how can I achieve what I found there in my universe?" It appears the difference between us is that you want a wholly liberal interpretation of the rules...

... consider this meta answer that relates to this discussion and remember that the Help Center prohibits mindless social fun. In other words, asking about something because you have a passing curiosity is prohibited... especially when it's a passing curiosity about a 3rd party world. There's supposed to be a purpose in the asking - and the OP did not include any such purpose.
