Yeah, I heard that in passing but I'm not willing to confirm it coz it's a rather hefty claim. I'd like to leave that one on the "maybe" pile for now, unless you can conclusively prove it for me.
I think they kinda just confirmed the Sheikah Woman to be the Goddess's Servant... Right?
It's said in the translation of the Lake Floria page.
No, but ONM just said that she's a character "we might remember from another Zelda game." Gee, wonder who that could be?
Oooh! Oooh! Impa!
At least I think so. I mean, she's supposed to be a Sage in Ocarina of Time, which would explain her long lifespan. So she's way younger in Skyward Sword and possibly is the very one who founded Kakariko Village after Hyrule was saved.
