- "One day, to escape from the fires of the war, a Hylian mother and her baby boy entered this forbidden forest. The mother was gravely injured... Her only choice was to entrust the child to the Deku Tree, the guardian spirit of the forest. The Deku Tree could sense that this was a child of destiny, whose fate would affect the entire world, so he took him into the forest. After the mother passed away, the baby was raised as a Kokiri. And now, finally, the day of destiny has come!"
- — Great Deku Sprout
During the Hyrulean Civil War, Link's Mother was gravely injured, and gave her son to the Great Deku Tree, in order to protect him from becoming another casualty of the war. The Great Deku Tree took him in, sensing he was a "child of destiny", and raised him as a Kokiri. Despite attempts by the Kokiri to tend her wounds, she died shortly after.
Link's Mother rides initially on horseback. When she reaches Kokiri Forest, just as she is about to faint, she hears small footsteps nearby and loses consciousness as many small figures appeared from the shadows of the trees around her. These small figures are the Kokiri, the child-like race protected by the Great Deku Tree, whose members are said to never age. They bring Link's Mother to their settlement deep within the forest and attempt to tend to her wounds, but her injuries are so great that they could do little but comfort her. They then take her before the Great Deku Tree himself, the guardian spirit of the forest that takes the form of a giant, talking tree. The Hylian mother regains consciousness as her last moments were nigh, and the Deku Tree converses with her concerning the future of her son. Knowing that her time is quickly drawing to a close, she reveals the child's name to be Link and makes it clear she does not want him to become another victim of the civil war that was tearing the realm apart. Her only option is to leave her child under the guardianship of the Great Deku Tree, who could sense that her child was one of destiny, whose fate would affect the entire world and change the course of Hyrule's future in years to come. Shortly after the Great Deku Tree promises to protect her child from harm and to watch over him as he grows.
Following the burial of the Hylian mother, the Great Deku Tree resolves to raise Link in accordance with Kokiri tradition, teaching him the means necessary to survive in the forest and to deter him from straying outside its borders until he was ready. The Great Deku Tree decided to not tell the child of his true heritage or what he truly was until the time was right and he was ready to know. The one problem with this omission of information, however, is the fact that every Kokiri has a fairy companion to accompany them throughout the course of their lives, meaning Link, not actually being Kokiri, was the only member of the tribe without one. For approximately ten years, the boy grew up amongst the children of the forest, not having any idea why he seemed somehow different from all the other Kokiri, nor why he alone did not have a fairy companion (he was referred to as "The Boy Without a Fairy", by the other children). Thus, the boy that would one day become one of the greatest figures in Hyrule's history vanished from the public eye, disappearing into the depths of the forest, not to be seen nor heard from again, for over a decade.
Link's Mother is a woman named Medilia, who lives in Calatia with the rest of Link's family.
