Seeking out Impa

Once Link made it off of the Great Plateau, he headed towards his next task: Seeking out Impa. He travelled to Kakariko Village, home of the Sheikah, and discovered the elder Impa in her huge house, accompanied by her lady-in-waiting Paya. Impa told Link that he had lost all his memories from 100 years ago, and that he should seek to find them so that he could prove he was a real hero and receive a long-lost gift of his. However, he would need guidance on where to go, meaning pictures, whose tune had not yet been unlocked.

Impa sent Link to the neighbouring village, Hateno, with the hopes that her sister, Purah, could help Link with the picture situation. After a long hike up a hill, Link was asked to carry blue fire up the hill again, to light the ancient power source that had long since grown cold. He took the blue flame from the ancient furnace, and again, climbed up the hill, this time more slowly.

When he got to the top, Purah agreed to restore the Sheikah Camera rune for a few ancient parts, and so Link gave her the parts and received a slate full of images, memories from long ago.

Link set out, recovered one of his memories with the help of the pictures on the Sheikah Slate, and once again went back to Impa. Impa was pleased, and finally told Link the story of long ago (Chapters 1-3) , and gave him a very special artifact; his Champion's tunic.

She explained that recently, the Divine Beasts had been more savage than usual, and recommended that Link go save the towns and cities ravaged by their own protectors. She also explained that, when Link would free a Divine Beast of its blight, the Beast would begin targeting Calamity Ganon to help Link in his hour of need while fighting.

So, Link set off to complete his first Divine Beast, completing quests along the way.
