The Nightmare Web of Adhe Wood

From publisher blurb: For 4-5 adventurers between 10th and 15th level, adaptable to lower tier play Located in The Vast north of the Sea of Fallen Stars, Adhe Wood is a small but deadly place. Legends swirl of a mysterious temple in Adhe Wood where statues of snakes hold massive emeralds. But the citizens of Sevenecho, the town nearest to Adhe Wood, seem to know nothing of this legend and refuse to speak of it. Travelers into Adhe Wood rarely return, devoured by the mutated spiders that lurk in the trees.
