The term fantasy is a loaded one - speak it aloud these days and, as if by magic incantation, you’re likely to summon into the minds of audiences a remarkably homogenous set of images from HBO’s Game of Thrones.  (A decade ago, those images might have come instead from Peter Jackson’s Lord of the Rings movies - though I doubt the impact would have been anywhere near as all-pervasive - and before that, you’d probably just have ended up with a mish-mash variance of porn images, to each their secretive own).
