From publisher blurb:

A new evil has emerged within northern Sivona. Rumors of fanatical dwarves marching north toward Darkhome have spread across the land. It is said that they transport a massive block of glass, shrouded in mystical gloom. Small villages have been destroyed as this growing entourage drives northward. Some say that each village is left with a contingent of fanatics, and a newly constructed shrine dedicated to an unknown god." For 3-5 players of 2nd to 4th level, B/X or 1E
