Whats a good name for a fantasy story world? And how can you make one?

I am writing a story and i cant figure out a name for the actual world. The town is South Hollows Berry Oak but i don't know what the world should be called. The main things in the story are elves, Nymphs, Pixies, and other creatures of fiction books. The land is like England. Forests and gr fields. What is a good name? Thank you.
