We die for The Watcher!
Orcish barbarians harry the northern trade routes through the cold north of the Theocracy of the Pale, serving a mysterious lord known only as The Watcher. Plagued by a series of bizarre animal mutations, the terrorized folk of the village of Tristor turn to adventurers to help them where hunters, vigilantes, and soldiers could not. Someone, or some thing, is sending a message to Tristor, and all fear the inevitable -- When the gruesome murderer claims its first human victim.
