The Mother and Child Isles (quadrant B2) is an island on the Great Sea. It is home to the Fairy Queen, who resides within the interior of the big island; the only way to get inside is to learn the Ballad of Gales from Cyclos, and then warp to the island. Fortunately, one of Cyclos’s cyclones can be found just a short distance from the island.
However, the Fairy Queen will only reveal herself after Link rescues Aryll from the Forsaken Fortress and meets someone else he needs to protect. The Fairy Queen grants Link the ability to use Fire and Ice Arrows.
