How do you know that Twilight is a fantasy epic novel?

Twilight is a fantasy novel because it envolves werewolves and vampires. But it doesn't involve ALL the legends about them. Legends like: -silver bullets kill the werewolves -full moon does weird things to them -humans can be turned into werewolves because of their bite -vampires melt in the sunlight The vampires in twilight are super speedy, which is not a legend, the werewolves and the Cullens become friends, there are realwerewolves in twilight too, the kind that Jacob is are called Quileutes and they're not half-men, half-beasts, they're gigantic wolves. Plus, they become wolves because of the blood bond in their tribe, not by "creating" wolves.
