From publisher blurb:
A 5th Edition Mini-Dungeon adventure for 4-5 characters of any level
In the shadow of snowcapped mountains, hidden deep within alpine forests, there is a strange and sacred site. Knowledge of its location echoes only through esoteric lore, but it was once known as Laorgyn’s Voice. An underground complex created in an age before mortals, the ancient sanctuary was manifested by powerful elemental spirits of earth in homage to their since forgotten goddess.
The adventurers may have learned of the location in a rare tome about lost cultures and ancient lore. The unknown author writes, “Laorgyn’s Voice be a place where the magic known by man was borne.”
