From publisher blurb:
At the waning of every year, as the sun grows closer to the horizon, and spends less time in the sky, there comes a time of terrible cold and deep snow to the lands of the north. The world waits with hushed breath for this, the longest night of the year, to be over. Soon, the sun will begin to climb higher each day, and the days grow longer. Although long stretches of cold weather are yet to come, this is the night in which winter’s back is broken. After tonight, the world turns slowly back to warmth and light.
But that is after tonight.
Perils of the Cinder Claws presents two holiday-themed adventures, "The Thing in the Chimney" (1st level) and The Nexus of Yule" (3rd level), as well as the Cinder Claws himself as a potential patron (complete except spells).
