The Dreamer's Shrine (5E)

From publisher blurb: A 5th Edition Mini-Dungeon for 4 Level 2 Characters This complex is hidden away in a dark corner of the world, underneath a major seat of learning in or near a large city. A former burial chamber, the sanctity of this complex has been ravaged by a fledgling cult and their vile leader, who have been growing in strength over the past six months or so. The PCs may stumble across the shrine whilst looking for a missing individual, or hunting for a particular item.
