Mother and Child Isles

The are a large island (the mother) and small island (the child) situated next to each other in the Great Sea in.

Features and Overview
The Mother Island is actually a Fairy Fountain which serves as the home of the Fairy Queen. However, it is surrounded by a high rock wall, so the only way for Link to access it is to use the Ballad of Gales, which is learned from Cyclos. This will warp him inside the Mother Island. Once Link rescues his sister Aryll from the Forsaken Fortress, he can enter the Mother Island to receive the Fire and Ice Arrows from the Fairy Queen. The Fairy Queen will not appear before Link until after he rescues Aryll.

On the Child Island, which can be easily accessed by boat, Link meets a Wandering Merchant. A Blue ChuChu, and Rown, one of the Korok inhabitants of Forest Haven, can also be found here.

Mother-and-Child Rocks
The Mother-and-Child Rocks are a notable part of Zora's Domain in. The structures can be found in the central waters near the base of the waterfall, and are the only area where the native Reekfish congregate. In the game, Link must catch a Reekfish in order to obtain the Reekfish Scent and thus find his way to Snowpeak Top.

The Mother-and-Child Rocks are an obvious reference to the Mother & Child Isles found on the Great Sea in ; however, it is unlikely that the two are related, as the rocks are much smaller in size than the islands. Also supporting this is the fact that it has been confirmed that and  take place at the same period in alternate timelines.
