No , really? That's where you draw the line? Can't think of any of the many other fantasy stories with "science fictions elements"? Not even the one where an order of warriors with magical power fight wars among the stars? Okay, that is too bad.
Next time someone pull up the good old "This doesn't make sense in a medieval setting" for Moonless age, a story that has been having giant machines, canons, ipads(before it existed), powered armors, bio-engineering and so forth from the very first chapter. Just use that demotivational style picture and fill in the text.
