Danse Macabre

From the publisher blurb:

Welcome to Danse Macabre, a bone-chilling adventure for oldschool RPGs inspired by Hans Holbein’s Dance of Death. In
this adventure, a noble knight hires the PCs to solve a grim
mystery in his hometown of Duskenville. People no longer
die, and the vengeful corpses of the recent dead are rising
from the grave to settle old scores.
Is this the work of a powerful necromancer, the result of divine wrath, or
something much older and darker? The truth may be hidden atop Mount
Brimovere, where an old castle watches over the city, like a silent sentinel.
Time is short. The undead grow bolder, and the city teeters on the brink of
chaos. If the PCs fail to break the curse, this danse macabre may never end
