In Mystery Of Wistimere, the Vermin took on a contract from the magistrate of Wistimere, and quickly found themselves entangled in violence and deceit. After discovering that a Troll they had once spared had risen as Undead through Zombie Rot, they began to suspect deliberate manipulation behind the plague. Their investigation into Mayor Perceval LaPall deepened when ledgers, missing animals, and his obsessive interest in Luana Yinshera pointed toward hidden wrongdoing. Choosing secrecy over warning, they allowed the Paladin Valant Vainglory to succumb to infection, then prepared to expose the truth by force.
Under cover of night, they infiltrated the Manor LaPall, subdued his guards, and uncovered a decade of journals detailing experiments in Alchemy, plaguecraft, and staged attacks meant to frame the Elf population of the Woods of Elenmyr. Beneath the estate, they found butchered elven bodies, caged undead, and Valant imprisoned after turning. In the ensuing battle, LaPall unleashed alchemical weapons and a Waxing Moonstone that forced Luana into transformation, leading to Valori's infection with Weretiger Lycanthropy and lasting heart injury.
Compelled to confess by Auberon, LaPall attempted escape amid released zombies before being burned alive by him, while the party destroyed the undead paladin he set against them. They presented LaPall’s body and confession as proof to both town and elves, securing their reward and preventing open war; Luana also joined the Vermin permanently.
