Dream of the Forgotten God

From publisher blurb:

Mini-Dungeon Adventure for 4 characters of levels 14-15

Dreams, while frequently unfathomable, often lead to interesting, if unexpected, situations. For the party, the chance to help a learned archaeologist study the dreams of a long-lost god seems almost too good to be true! However, their sponsor cannot quite explain what they will find once they venture into a desert mausoleum. Perhaps his guidance was simply “all in the mind.”
