My first night ruuuuuuun

It’s gonna be through a graveyaaaaaard

From the information site about the run, where they talk about some “features” of the graveyard:

This underground tomb, belonging to “E.A. Fisher” and
apparently constructed in 1902, has been sealed – the stairs down to the
entrance filled in with dirt, and the windows on top plugged with
cement. This is commonly done to reduce maintenance costs, after an old
in-ground mausoleum is filled to capacity and unlikely to receive
visitors.

Sure. That’s why they buried and sealed a stone vault full of dead bodies. There’s definitely not an eldritch horror lurking in the Fisher Tomb.
