Creeping Death [PDF ebook] 

In the notorious slums of Mendulia’s Rock, a series of heinous murders worries the city authorities. All clues would lead to believe that a serial killer is behind the murders were it not for some minor evidence that brings to mind something far more sinister. To find the truth, the heroes will have to dive deep into the murky waters of the Slums district.
Aimed at characters from 1st to 3rd level,  
Creeping Death is the first adventure set entirely in the dark world of Neir (setting 
La Notte Eterna) and based on Dungeons & Dragons 5.0 edition.
