You reach the village after a long day of adventuring or travel, in high spirits. But the street is dark and cold. You think at first you see a dog rummaging through a pile of kitchen scraps; then you realise that it's a wolf, the first of many.
When you break into a house, you find everyone asleep, in a slumber that cannot be broken. Anyone with witch-sight can see the larvae, the spirit-wyrms, coiled about the bodies of the sleepers. But no common sorcery can dismiss a wyrm without destroying the mind of the sleeper.
Eventually, you might find the broken crypt in the kirk-yard and the body of the poor, damned fool (an adventurer like you) who opened it. Soul-burn is a hideous death.
There are clues scattered about the tomb and notes in the priest-house that might lead you to the legend of the soul-bell. But an interfering priest of the Narrow Faith cast that relic into the ravine a hundred years or more ago, and the ravine is haunted by grimelocks, naggs, and worse.
But it might be worth finding the bell, and letting it ring from the spire before dawn. Before the spirit-worms pupate and hatch...
