The Quitspirus Cluster is situated on the edge of a virtually solidified sludge sea called the the Worldsump Ocean. At one time, when the sea was still navigable, the area included vast dockyards. These now remain buried deep within the undercity of the centrally located Quitspirus Hive. This hive has five great spires - hence the name which means "five towers" in the local dialect and which gives its name to the whole cluster. The cavernous warehouses of the ancient waterfronts have been the scene of many savage gang wars.
