Gravediggers had the unenviable job of preparing the resting places of a settlement’s dearly departed. Historically, they weren’t particularly well-paid, although they could become respectably wealthy during times of abundant work, such as periods of plague. In regions such as Eastern Europe, some believed that the dead could rise from a grave and prowl the countryside, feasting on the living (some researchers suggest that these beliefs gave rise to our popular vampire legends); in such cases, gravediggers shared the responsibility with clergy of interring the dead in such a manner that would make such emergence impossible, typically by decapitating the corpse and turning the head face-down, and weighing down the suspect body with heavy stones.
In a D&D game, gravediggers are uniquely qualified to advise heroes about town residents passing to the next life. This information can include common causes of local death, determining how long something has been dead by rate of decomposition, the grave visitation habits of townsfolk, and grave robbing, along with reporting evidence of fantastic elements such as foraging ghouls, packs of giant rats and evil cult activities.
