This sub-genre is a fusion between the two main genres. It represents works that use main elements of both to create a story that is (for example) futuristic and technical in tone, with fantastical sub-plots and characters. Arthur C. Clarke once said, “any sufficiently advanced technology is indistinguishable from magic”, which might make the sub-genre easier to identify! Some would argue that there are even “sub-genres for the sub-genre” in this category, but for our purposes we will stick with the high-level definition given here. Anne McCaffrey‘s Pern novels are good examples of this sub-genre.
