Feywild

The Feywild exists in parallel to the Material Plane, an alternate dimension that occupies the same cosmological space. It mirrors the material world but turns its features into spectacular forms. Life just seems more vibrant here. Portals, such as a clearning, a pool of water, or a circle of mushrooms, to and from the Feywild are known as fey crossings. A crossing might only open during a full moon, on the dawn of a particular day, or for someone carrying a certain type of item.

Creatures have disadvantage on saving throws against being charmed and any effect that inflicts the charmed condition has its duration doubled.

A creature that leaves the Feywild must make a DC 10 Wisdom saving throw or lose all memories of their time in the Feywild. Fey creatures automatically succeed this saving throw.
