The voice of the Spirit Tree in the forest of Nibel narrates the story, about when Ori fell from the tree during a storm as a newborn and was adopted by a sasquatch-like creature named Naru, who raised Ori as her own. A cataclysmic event soon makes the forest and its food supply wither, and Naru dies. Newly orphaned Ori was left to explore the forest on his own. After collapsing near the Spirit Tree of the forest and being restored to life by it, Ori later meets Sein /saɪn/, a being who both guides Ori on his adventure and attacks enemies. In order to restore the forest, Sein guides Ori to recover the light of three main elements supporting the balance of Nibel: Waters, Winds and Warmth.
