The Legend of Zelda: Breath of the wild

"In the distant past, the many races of Hyrule lived together in harmony, the Sheikah's blue aura providing life to the land, and everyone benefited from the Sheikah's advanced technology. That all ended when a beast that came to be known as Calamity Ganon appeared. 10,000 years later, after having reverted to a medieval state, the kingdom of Hyrule rediscovered the ancient technology left behind by their ancestors through excavation. Upon reading the prophecies their ancestors had left behind, they learned that Calamity Ganon would return, and that Hyrule would require the mechanical Guardians and Divine Beasts to stop it. Key members of Hyrule's various races were assembled to pilot these ancient machines and given the name pilot Champions. The Hero, the Princess, and the Champions attempted to stop the evil, but ultimately failed. The Calamity Ganon had turned the Guardians and Divine Beasts against the kingdom of Hyrule, causing it to collapse. The Hero was gravely wounded and taken to the Shrine of Resurrection. The Princess then used the last of her power and managed to temporarily seal Calamity Ganon inside Hyrule Castle. In the present, 100 years later, an amnesiac Link awakens from a deep sleep as a mysterious female voice guides him to the now ruined kingdom of Hyrule. He meets an old man and learns that Calamity Ganon has been sealed in Hyrule Castle for one hundred years. Although trapped, Calamity Ganon has continued to grow in power, and Link must defeat it before it breaks free and destroys the world"--Wikipedia.
