SPOILERS Better idea, *Stemming from the lack of sheikah tech in SOR* In the shrine of resurrection, there's no tech. My theory is, it was meant to disappear AFTER the hero saved Hyrule, similar to the monks. But, if you look at the lightroots in the depths, there is sheikah tech, and when Mineru's mech teleports to you, it teleports to you similarly to link, fading into little blue strands, then materializing. SO my theory is, The Sheikah derived from the Zonai, working Zonai tech into their creations. The Shrines of Light had to have been in Hyrule from the beginning because, under most shrines, there is a light root. BOOM
