This is a scenario based on the city of Ankh-Morpork in the best-selling discworld novels by Terry Pratchet.
Described as the nasal equivalent of a fireworks display, Ankh Morpork has been dubbed, "The Carbuncle of the disc". Home of corruption, crime and murder, Ankh-Morpork is built on the banks of the pestilent river Ankh, which is the only place in the multiverse where detectives can chalk the outline of a murder victim on the river.
