Quote from : Nausicaä of the Valley of the Wind Movie

Yupa: In the midst of my travels, I heard of an ominous rumor... It said that a monster from the ancient world had been excavated from beneath the city of Pejite where it had been sleeping.
Mito: A monster from the ancient world?
Yupa: It's a God Warrior.
Mito: A God Warrior? You mean, the ones that burned the world in the Seven Days of Fire...? This thing...!
Yupa: All God Warriors should have become fossils. But this one managed to sleep underground for 1000 years.
Mito: Now that you mention it, it does seem to have a human form.
