Some weeks ago, a tiny sliver of shadow crept into Yarralanya Swamp. It fed on the worms, then on the fish and snakes, growing larger over time until it threatened the lives of the swamp folk, who took up their weapons and fought back, to no avail. In order to buy time for a second attempt, the swamp folk began to steal livestock from the nearby village to satiate the beast’s hunger. After all, who but those villagers could be responsible for unleashing this threat? Soon after, a band of adventurers visiting Rishel’s Hollow find themselves tasked with a simple mission: end the theft of cattle by whatever means necessary. This adventure should run for 3-5 hours, either as a standalone one-shot or as part of an existing campaign, especially one featuring creatures from the Shadowfell or the experiments of a mage. Encounters assume a party of 4-6 level 4 characters.
