The Shrine of Glass-Spire Forest

From the Publisher's Website:

"The Shrine of Glass-Spire Forest" is a Chaos Scar Side Trek/adventure designed for five characters of 2nd level. This scenario consists of a skill challenge and two encounters, so you can run it in the Chaos Scar campaign or as a short stand-alone adventure.

"There are many strange places beyond the great wall, that edifice which has spawned a thousand stories. But perhaps none are so strange as the place that adventurers call "the glass forest." Those few who have returned from journeys in the great valley tell of the keening that arises near this strange locale when the wind blows to the east, as if a thousand wind chimes had been set in motion."
