The Frigid Feeding Grounds: Winter Encounter for 5e

From Introduction:

A cabin in the snowy wilds was once a rest stop for travelers but has recently become infested with icy undead. They use it to draw in prey and feast on frozen bodies.

The tundra claims many victims. Scything cold fills vast plains of white wasteland, pierced by mountains and forests. The elements dig beneath armor to drain travelers of their strength. Bones ache and muscles stiffen. But worse than all of that are the creatures that call the tundra home. Twisted by their environment, they share its unfeeling nature with the addition of bloodthirsty hunger.
