From publisher blurb:
The Demon Lord’s shadow looms over Urth, growing stronger with each passing day, and every terrible deed and sacrifice performed in his name. As winter falls across the lands, old legends stirred by the Shadow come to life once more. Ancient evils that few remember rise again to resume their nocturnal wanderings, spreading darkness, suffering, and death wherever they roam.
Written for a group of expert characters, He Sees You While You’re Sleeping is set in the small village of Hund, where a terrible monster threatens those among them who are the most vulnerable: their children. A fledgling cult has taken root in an abandoned asylum just outside the settlement, engaging in vile and dark magic to harness the essence of a horrific demon called the Krampus: a malevolent entity infamous for hunting, terrorizing, and killing children all across Rûl.
The group completes the adventure when they defeat the Krampus or at the toll of midnight on Krampusnacht, which is the beginning of the winter solstice.
