The PennyRoyal Banshee is a supernatural brothel, run by a human named the Hag. When a Maggopod called Muck seeks to mate with another of its species, the only option is to enter the Banshee in hopes of finding a fellow Maggopod under the Hag's employ. With the disreputable O'Grady's Enchantments swiping all of the Maggopods off the streets, Muck has to tread carefully, and be wary about who can and cannot be trusted.
