Reasonable is always appropriate to the discussion.Literally "mundane" would be even more restrictive than "realistic," and even more inappropriate to a fantasy setting.
So "not magical" is a more reasonable way to take it.
Not that "reasonable" is any more appropriate to these discussions than "realistic," either.
And quibbling over the term being used is just a waste of time.
The thread title presents mundane and supernatural as opposites, and the OP makes pretty clear what they mean by the question. We can all just engage on that basis.
