From the introduction:
REQUIREMENTS/SUMMARY/OBJECTIVE
A character (PC or NPC) has died in the last few weeks under strange circumstances, killed by a ghoul or unknown creature of darkness, if possible. PCs must be willing to risk bodily harm and enter a ghoul warren in order to help the (un)dead character achieve final rest or be restored to life (optional) via the Wight/Ghoul Lord's ritual.
INTENT/FUNCTION
This is a fantasy scenario originally written for the Warhammer Fantasy Role Playing Game with some influence from H.P. Lovecraft and the Call of Cthulhu RPG, specifically his unusual depiction of ghouls as intelligent and normally nonthreatening to the Living.
A "one-off" or "in-between" to allow a quick one-session scenario requiring little preparation or maintenance, which can be run as a component of or independently of any other ongoing campaigns, scenarios or plots. Its a pretty free-form scenario idea designed to be adapted and modified as needed by the GM.
