From publisher blurb:
About two days out of Lowhollow, on the way to Redmarsh and Lake Bloodmoon, lie Mount Dath and Elp's Climb. Between these two snowcapped mountains, the Gnarlay Wood is settled. The dominators of Peakvale give these forests and their surroundings some room, not only because of the ork-kindred bandits that prowl the roads or thereabouts, but because of the Iueresa elf clan that dwells within the forests proper. Somewhere in the midst of these forbidding wilder lands lies the [Temple of the Hag].
This is an adventure for common kindred delvers of levels 3 to 4 using 7.5 edition rules, although it is easy to modify for 5th edition.
