The Empire is a sea of trees and wilderness, punctuated by all too seldom islands of civilisation and security. Its roads are winding, muddy tracks, plagued by bandits and worse. No wonder then that most who can afford it travel by river barge, and the waterways of the Reikland are alive with trade, travel, crime and adventure. Most major settlements of the Empire are built upon the banks of one of the great rivers that flow through the nation. Together these rivers form an extensive network, tying the vast Empire together.

„Something Knocking” takes place on just such an artery of trade and trouble. A band of pirates has been the cause of a great deal of trouble along a stretch of the river, and strange phenomenon has been linked to their activities. The Characters may have to form an unlikely alliance and dip into the murky waters of folklore and magic to solve a mystery and bring the reavers to justice.
