You've gotta be careful around the Fey. You don't want to suddenly be involved in a contract you didn't even know you were negotiating for. But it's the Fey that you'll be dealing with in The Wild Beyond The Witchlight, the new D&D adventure available now from Wizards of the Cost.
From the website:
Once every eight years, the fantastic Witchlight Carnival touches down on your world, bringing joy to one settlement after the next. Its owners, Mister Witch and Mister Light, know how to put on a good show. But there’s more to this magical extravaganza than meets the eye!
The carnival is a gateway to a fantastic Feywild domain unlike anything found on the Material Plane. Time has not been kind to this realm, however, and dark days lie ahead unless someone can thwart the dastardly schemes of the Hourglass Coven.
The Wild Beyond the Witchlight takes adventurers from the Witchlight Carnival to Prismeer, a Feywild domain of delight, and is designed for characters of levels 1–8. This book comes with a poster map that shows the carnival on one side and Prismeer on the other.
