The story takes place in a village in Ravenloft. The party has been invited to accompany the young couple Burgomaster Alexandru and Mihaela Nichitovich [ni-KEE-toh-vich] of the hamlet of Nichitovia [ni-kee-TOH-vee-uh] to Rosenwald, a deeply religious community. Alexandru has asked the priests of Rosenwald to conduct a traditional ritual to gain him the favor of the Morninglord for his tenure as burgomaster. This is a ritual all burgomasters traditionally receive, including his late grandfather, who is entombed at Rosenwald. Father Petre and Sister Elena of the church of the Morninglord loosely run Rosenwald. They offered to throw Alexandru a banquet at the House of the Morninglord before the ritual, set to take place during the next full moon. However, all of the clergy have secretly become afflicted with the aswang curse. Father Petre is a halimaw and Sister Elena a kubot, both of whom gained their powers through dark pacts with demon lords of the Abyss. The other priests and acolytes are busos, survivors of encounters with roaming tigbanuas, who found sanctuary with Petre and Elena. The pair refer to these busos as their flock, and plan to feast on the guests after the banquet.

Genius rogue artificer Ichabod Russet hired ten of his most brilliant colleagues to collaborate and build the greatest automaton yet invented: a clockwork beholder. He dreamed their invention would catapult him into stardom and wealth. In a secret mountain laboratory under Ichabod's direction, each scientist devoted themself to developing one ray for the creature's mechanical eyes -- but when the mysterious tenth ray was added to the automaton, it became too powerful. The clockwork beholder broke free during QA testing and destroyed half the lab. Only a few of the artificers escaped to tell the tale, and for the most part, they're keeping their mouths shut.

The Dysmal Swamp is a coastal wetland that stretches over 100 square miles. Devoid of any urbanization, the ecosystem enjoyed its dank sanctuary. A community of bullywugs called the swamp home for generations, hunting and maintaining the balance of the land. The land also appealed to the Belange Company, a wicked fey-run enterprise making cheap magic items, who needed a secluded location far from both thieves and oversight. When the Belange Company established their magical workshop in the swamp, the bullywugs attempted to drive them off. However, the Belange Company’s supply of magical items provided enough firepower to protect their endeavor, and many bullywugs fell in the initial conflicts. The Belange Company began crafting scores of magical items to be sold across the region, using a cheap alchemical process that produced a nasty liquid byproduct glowing with chaotic magical energies. Rather than devise a new process, the Director decided to discharge the waste into the swamp. As production increased, so did the pollution, and the sludge began to warp the wetland. The region’s typically reclusive bungisngis population became aggressive. It is only a matter of time before these mutated swamp giants lay waste to bullywugs.

The nearby jungle is growing at a disturbing pace -- overnight, whole villages have been swallowed up by creeping vines. Rumors say the source is a corrupt and powerful temple deep in the jungle. In reality, the blight lords of Talona created a monstrous corpse flower and imbued it with the power of a cursed gem from an ancient temple of their goddess. After the blight lords released it into the forest, the corpse flower bent the surrounding jungle to its semi-sentient whims, recreating the temple out of plant life -- with an insatiable hunger for expansion.
