"Today I met with Impa of the Sheikah tribe and
began my research into the ancient technology in the earnest. Impa introduced me to Purah and Robbie,
other respected members of her tribe. Tomorrow I
embark on an excavation with them. We hope to find ancient tech with which to operate the Guidance Stones."
