How about a set of fantasy books or graphic novels that he can read and explore? You could also get him a fantasy movie box set, such as Lord of the Rings or Harry Potter. Another idea could be to get him a fantasy-themed board game, like Dungeons and Dragons or Betrayal at Baldur's Gate. If he likes to build, you could also get him a fantasy-themed LEGO set, like a Hogwarts Castle or a Lord of the Rings Battle. Finally, you could consider getting him a custom-made fantasy-themed piece of artwork to hang in his room, which he would surely cherish.
Or you can get him a star map with the date when he was born.
