The world of dreams reveals itself in many ways. For Cass it's a place to escape the dull grind of her lonely life, a place where she can run the twisted streets that curl off the Boulevard and live out her violent fantasies. For Detective Babbage, it's a beat to walk, a dark, dangerous environment for him to hunt down his clues and get closer to who or what is haunting its streets. For Adlai, sitting drunk in a bar on the border between Milky Way Boulevard and the real world, it's a place to watch his creation transform itself from a theatre of heroism into, hopefully, something more vital. The one thread that pulls them together is the nightmare vision walking the streets, a rogue musical virus that infects users and feeds off their fears, growing stronger with each kill. It has been designed to take down the Grid, a powerful governing entity on the Boulevard, but this weapon has become twisted, harvesting any user it comes across, and threatening to take down the entire structure of the Boulevard itself.
