Eldraine is a plane inspired by fairy tales, and in the latest set Wilds of Eldraine, Magic the Gathering is putting into play many of the more 'out there' elements of fairy tales. From witches covering the world in a curse to strange creatures like a Goose Hydra, this new Eldraine set pulls the world further from Arthurian Myth and more firmly into the more general realm of European folklore and Grim's fairy tales.
