Publisher: Wizards of the Coast, 2021. A levels 1–8 adventure centered on the Witchlight Carnival, a traveling fair that serves as a gateway to Prismeer, a Feywild domain ruled (and warped) by the Hourglass Coven of hags.
Tonally whimsical/fairy-tale, with player choice heavily shaping the outcome of Prismeer’s ruling archfey.
