Overview

Willowmere is a small town perched along a bend of the Lyth river, famed for its market, hot springs, and stubborn pride. A sudden plague—fever, coughing, ash-like spores—has gnawed its spirit to bone. The mayor, Honora Kestrel, pleads for capable adventurers to halt the spread, uncover a root cause, and return the town to health before a quarantine seals the gates forever. The mystery blends sickness, superstition, and a secret cult, forcing players to weigh mercy against menace as they chase rumors through fog-bound streets and shadowed ruins.

Setting and tone

The campaign blends village politics with eldritch menace. Moral choices matter: who gets treated first, who is blamed, and what line is drawn between science, magic, and superstition. The land is lush but warped: marshy thickets harbor haunting whispers, quarry caverns yawn with forgotten risks, and an old church crypt hums with ancient power. Nightly bells, market fever, and the rumor of a “cure” that does not quite heal all deepen the tension.

Key locations

• Willowmere Town Hall: where the mayor and council wrestle with quarantine edicts and fear of panic.


• The Clocktower Quarter: the source of rumors; a dying apothecary keeps whispered remedies.


• Marshline Woods: home to Moonleaf, a rare herb needed for cures, guarded by warding spirits and misdirection.


• Old Church Crypt: hidden rites and a sealed oath bound to the plague’s origin.


• The Rusted Quarry: the likely cradle of the plague’s magic beneath collapsed veins and echoing shafts.


• The Gatehouse Ruins: a ruined beacon that once watched the river—now a focal point for a cultic ritual.

The main quest

1) Gather clues from doctors, apothecaries, and town leaders to map the outbreak’s spread. 2) Retrieve Moonleaf in the haunted Marshline Woods and a ritual scroll from the Crypt. 3) Uncover the Sable Veil cult’s plan to awaken a buried plague-spirit beneath the quarry. 4) Enter the quarry and confront the cult’s leader, a corrupted cleric, defending a sealed chasm-passage. 5) Perform the purification rite at the town square to craft a cure and lift the quarantine.

Side quests and investigations

• A missing child of a fisherfolk family may be infected; tracing them reveals the cult’s circus of misinformation.


• A rival alchemist offers counterfeit cures; exposing him earns a fragile alliance or a costly betrayal.


• A haunted beacon in the Ruins hints at an ancient pact that allowed the plague to spread; breaking the pact weakens the source but unlocks dangerous truths.

Hooks and central events

• The plague worsens as the moon wanes; townsfolk grow desperate for a miracle.


• A stranger in the inn carries a sealed letter from a distant temple, hinting at the cure’s prerequisite ritual.


• If the players delay, the river gate will close to protect Willowmere, trapping them with the growing outbreak.

Rewards and outcomes

• Gold, influence, and favor with the mayor; access to a private apothecary stash.


• A magical lantern that sheds “truth-light,” revealing hidden lies and illusions.


• Potential long-term boon: one character may gain resistance to magical corruption or a minor healing aura tied to the cure.
