One Night in Mourning

From publisher blurb: On our way into Mourning, the druid noticed none of the local farms kept sheep, or cows, or any livestock at all. Boy, do we wish we'd paid more attention at the time. Now the full moon is up and howls are rising from the entire countryside... This is a system-agnostic dungeon designed to slot easily into whatever kind of campaign you might be running. Use it as a human settlement, a random wilderness encounter, or a challenge between your party and that healing break they're so eager for.
