Wonderland is the magical and madness-filled location which the life of Ever After relies on. Without Wonderland, the fairytale world would no longer contain magic. The Evil Queen took over Wonderland and put a curse on it. Wonderland became poisoned, causing the Wonderlandians to leave their homeland and flee to the world of Ever After. As of Way Too Wonderland, the curse was lifted by Raven.
The magic of Wonderland Grove was slowly fading away, and once gone, the magic of Ever After would fade as well. Wonderland Grove is the one part of the Enchanted Forest which links the students of Ever After High to Wonderland. In "Maddie's Hat-Tastic Party," Maddie and her friends help restore it with madness. The students have their own tea party in the heart of Wonderland Grove, but Cerise does not join in. Raven urges her to dance and take off her hood. The students stand in awe, but they believe that Cerise is wearing fake ears to liven up the party. The life, madness and magic of Wonderland Grove are all restored and the students continue to party happily.
All but one of the portals to Wonderland have been shut off due to the Evil Queen's reign. One portal was left open so a little bit of wonder could flow into Ever After from Wonderland. If that portal becomes blocked the magic of Ever After fades away. In Spring Unsprung the well is blocked and the wonder from Wonderland is drained from the Land of Ever After. The block was removed and Ever After gained it's magic back.
In Way Too Wonderland, a villain plots against the Queen of Hearts and a twist of fate shows Maddie, Lizzie, Kitty, Raven, Apple, and Briar the way to Wonderland, where they meet new characters there. Revealing the plot and defeating Courtly Jester, who was behind it all, Raven lifts the curse over Wonderland, opening the portals to Ever After.
