Ruins at Wolf Creek

Publisher's blurb:

Ruin at Wolf Creek hints at two of the boss creatures in the area, the death stalker brothers, undead rangers, Maleck and Obadiah. A glimpse at what they do and what's to come. Otherwise this is a found site, a place the party finds while exploring. There are some nasty creatures here that can devastate a party. Image the party's delight and terror as they cross the creek and see a rust monster. That should put some poop in their britches. I haven't used one of those critters in years.
