The Everfree Forest is a is shown to be located outside of Ponyville, and is the home of the zebra Zecora. Most ponies are somewhat unnerved by the forest, as unlike the rest of Equestria, it apparently does not require pony intervention to keep nature in sync. The forest is stated to be home to many strange or dangerous creatures. Fluttershy lives in a cottage at its edge, but states that it is much too dangerous for most ponies.
At the forest's center is a magical tree known as the Tree of Harmony. This tree was the source of the Elements of Harmony, and was responsible for keeping the forest in control. The elements were removed by Luna and Celestia to battle Discord, but the tree would keep the forest in control for at least one thousand years. However, when the tree's magic was drained by Discord's plunder seeds, the forest begins invading, taking the form of thorny, black vines which are nearly impossible to stop. The forest is only contained when Twilight Sparkle and her friends return their elements to the tree.
