From publisher blurb:
'Blood in the Snow' is a quick-adventure for a party of four 3rd level characters. Very little adaptation should be necessary to use in any campaign setting.
Adventure Background
It started with a harmless contest between two neighboring communities: Edmiran and Cantre. The people of Cantre, having lost one too many years, returns home full of bitterness and ire. Something unseen and unknowable lights the fire of their hatred and promises them the power to finally bring down their long-term rivals once and for all. The people, blinded by their pride allows this entity to trick their sense of reason. Several nights later, while Edmiran attempts to discern why their neighbors have all grown quiet, a series of attacks begin to plague them nightly.
Every night, violent snowmen attack the people of Edmiran, only to leave behind pools and puddles of water when morning comes. Unable to withstand the nightly barrage any longer, its people call forth a group of adventurers to aid them in their desperate plea to be saved from the monstrous snowmen before both communities are no more.
