Maca is a Korok that lives in the Korok Forest. Maca can be found outside the entrance of the Great Deku Tree, and provides Link with information about the forest and Master Sword. Maca tells Link that the Master Sword may lose power if overused, but will regenerate over time. When Link asks about leaving the forest, Maca questions why he would want to leave this perfect place. Regardless, Maca tells Link that he can leave the woods by warping through the mouth of an Ogre Tree east from the sword pedestal.
↑"Well the Master Sword is a very special weapon, but it can lose its power if you overuse it. When that happens, don't panic. All you have to do is wait for its power to regenerate." — Maca (Breath of the Wild)
↑"If you head east from the sword pedestal, there will be a sign on your right. Climb up the hill on the right side of the sign, and you'll see an ogre tree. If you walk into that tree's mouth, you'll *whoosh* be taken to the entrance of the woods." — Maca (Breath of the Wild)
