What is "fabletown"

Fabletown is the fictional, clandestine community of "Fables" resident in New York in the Fables comic book universe. It exists in two locations, one being Bullfinch Street (a reference to Bullfinch's Mythology) in the Upper West Side of Manhattan, and the other on a large farm in upstate New York, protected with magical spells that repel non-Fables (generally referred to as Mundanes, or, informally, "Mundys").
