Dispatched on a mission for evil museum curator Karver Craft, a Dark Fairy called Nero hunts the streets of Philadelphia for the curator's latest prize: a Faun.
 
But finding the Faun is the easy part. Nero's greatest challenge will be returning the creature to the museum while dodging a menagerie of fellow denizens of the wild and whimsical fantasy world known as the Underland. Failure means one thing: taking the faun's place, imprisoned among the shelves of The Museum of Mythological Wonders.
