This is a Dungeon Crawl Classics adventure set in Lankhmar for level 2 adventurers. You will need the DCC core book.
From the publisher:
A corrupt Duke of Lankhmar’s foibles paraded before the masses for their entertainment puts an acting troupe in trouble. Threatened by the insulted Duke and his private guard, the performers need assistance to make it through their final performance of “The Fiascos of Duke Hogfat.” With nobody else to turn to, the troupe hires the PCs as their evening’s protectors. Will the play end in a standing ovation or will the Duke and his thugs bring down the house on the troupe and their defenders?
