Some time ago, before the king of Hyrule unified this country, there was a fierce war in our world. 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!
