What about "Once Upon a Time"? From a few fics I've read it seems like an interesting setting for Xander to interact with or with his luck at times, to have come from where the inhabitants of the town of Storybrooke originate from pre-curse, the Enchanted Forest.

Author's Response: This should really be on the list instead of in a comment, but i've barely seen any of OUAT. As in part of one episode. So probably not with me at the moment. but thanks for the idea.
