Faeries are among the oldest beings known to Hylians and for as long as anyone can remember, they have always helped those in need. You will find that Faeries and Fairy Springs are abundant in the Land of Hyrule. It's very important to know all of the locations where Faeries appear.
Small Fairies float around the land of Hyrule and usually occupy springs in groups. They restore up to a maximum of seven lost hearts, and can be captured by a net, and stored in a bottle for future use. If you die in the middle of battle, and you have a fairy in a bottle, the fairy will release itself and bring you back to life before flying away.
Larger human-sized Faeries occupy fixed locations in certain springs throughout Hyrule. They will completely restore your health, but you must come to visit them at their Faerie Spring in order to receive this benefit. Faeries are devoted to local Faerie Queens who will also aid you in your quest.
