From publisher blurb:
There is a terrible creature known as the Wolf who hunts everything that moves, man or beast; a thing whose true form is largely unknown thanks to the sewn hides of its prey that it wears. While a thing that displays the flesh of thinking folk would itself be macabre, the Wolf is not just a strange, cruel hunter. This creature can adopt the traits of the kills it wears, growing in power as it continues its slaughtering predilection. The ghoulish mysticism behind its tales dares heroes and mercenaries of great skill, drawing them into its path, just the sort of prey it has grown to favor.
The Wolf is a Q-Encounter, or Quick-Encounter, that can be run for a group of four to six players with 15th-level characters. This encounter would be considered a ‘medium’ to ‘hard’ encounter.
