Pandemonium is an alternate New York City where all the supernatural beings of Earth are trapped — actually it's not too much different from the real Big Apple.
There are five cities:
ShadowShade (Manhattan) - a fast-paced metropolis teeming with all manner of supernaturals. Jack has an office in Midtown.
The Broken Lands (Brooklyn) - a hellish landscape that's home to demons, ogres, vampires and goblins.
Monster Island (The Bronx) - a mountainous and wild region that's home to misfit and loner creatures such as Yetis and Sphinxes.
Witch End (Queens) - a suburban city that most closely resembles old Earth, home to the human witches, warlocks and sorcerers.
The Red Garden (Staten Island) - a mostly swampy, forested place that is a never-ending battlefield for the werewolves and fairies that live there.
