That Poor Girl (2020)

From publisher blurb:

So, you've agreed to run a game today and you have not had time to even think about an adventure. Don't freak out. We have you covered. This document is all that you need. Run this adventure. It will be over in one session. Then you can get back to your own evil machinations next session.

Eva, the daughter of a prominent local businessman in a small frontier town, dies tragically while she underwent surgery. The girl was only thirteen years old and her parents were stricken by the loss of their only child. Her father built a memorial for her next to the small prairie cemetery where she was buried. It was an open brick chapel meant to be used for funerals or an occasional church service.

As the years went by, given the chapel's isolated location, people began using it for disgraceful purposes. Vagrants camped in the chapel. Local youths gathered there for sinful parties. Someone even dug into a grave looking for valuables. The family had no choice but to have the place sealed up with bricks.

This did not mean that the place was not still being used...

While this adventure is set in the Boot Hell campaign setting, it can easily be used in any sort of Western steampunk or horror roleplaying game. It uses 5th Edition SRD rules as a default.
