Have you watched population a so-bad-it's great mystery movie called "Population 436" ? The eerie little town is called "Rockwell Falls" & I always though that was a pretty & ominous name at the same time.
"While traveling to Rockwell Falls in an assignment of the US Census Bureau, the surveyor from Chicago Steve Kady has two flat tires nearby the small town. The local Deputy Bobby Caine brings him to the town and the Mayor Grateman lodges him in a farm, where the gorgeous Courtney Lovett lives with her mother. Steve finds that Rockwell Falls, considered by the locals as the most perfect place on Earth, has the same population since 1860 and sooner he discloses the meaning and the dark secret of their creed of solidarity and steadfastness."

"Ah, I can see you like pokemon? I like pokemon too!"

( I stuffed up the multi quote)
Thanks for the feedback!
The only Poke'mon town name on my list was Laverre though. All the others are from stories, real towns or my imagination.

I do think Laverre is perfect for what you are going for as it's the fairytale town, but before hand (the route leading to it) is a ghost section with an abandoned playground & a swamp.
Then it's all butterflies, fairies & mushrooms! So it combines eerie with beautiful.
I also liked the "Mistcove" suggestion.
So many cool ideas in this thread.

Can't wait to see what you pick.
