From the introduction:
Magister Schlect, a founding member of the Cult of the Crimson Plague, with the assistance of the Bailiff of Trotteldorf and other cultists in the village, has summoned a plague bearer to sow the rye fields of Trotteldorf with a fungus that produces an insidious disease known as nergotism. Life in Trotteldorf goes “a-rye” as the villagers have begun to suffer the disturbing and sometimes fatal effects of nergotism. Furthermore, the Bailiff has provided an infected harvest as Trotteldorf’s tribute to the Raven Knights of Morr, to avenge the downfall of his family as one-time rulers of the lands now held by the Knights. If the adventurers don’t stop the Bailiff and Schlect, on the night of All Soul’s Eve, the plague dead will rise to destroy the village.
Chaos in the Rye is an adventure for 4-6 characters with more than one basic career behind them. It is set in the sleepy village of Trotteldorf in Stirland, but with a little effort could be moved to any suitably rustic border region of the Empire.
