If it has horses and swords in it, it's a fantasy, unless it also has a rocketship in it, in which case it becomes science fiction. The only thing that'll turn a story with a rocketship in it back into fantasy is the Holy Grail.
Debra DoyleIf there’s a zeppelin, it’s alternate history. If there’s a rocketship, it’s science fiction. If there are swords and/or horses, it’s fantasy. A book with swords and horses in it can be turned into science fiction by adding a rocketship to the mix. If a book has a rocketship in it, the only thing that can turn it back into fantasy is the Holy Grail.
