The small town of Dellburg is a trading stop, a waystation upon the Imperial Highway. People stop here, they have a drink, they take a load off. The Town's most notable feature is that there is running water and sewer sanitation, unheard of for a town of this size in the middle of nowhere. Dellburg though, is hiding a deep dark secret. Under the town is a Warren of Skrzzak, the ratmen that most people will tell you are not real. In fact, they are deadly real and what happens below is about to spill out to the land above. Night of the Vivimancer is an adventure for Zweihander Grim and Perilous RPG designed for a party of 4-5 Characters at the end of their Basic Tier. The adventure should take 3-5 sessions to finish, and can be played on it's own or dropped into a currently running game. - from the publisher's blurb
