Finally met the Sphinx. It's true that it's somewhat hidden, wouldn't surprise if some people would miss her completely on a first playthrough.
The riddles are cool. But man, as someone who likes having a bit of weed while playing, the riddle of rumination was way too much for me. Had to look up a guide to have a list of every seeker token in the first are and try and remember which one of those was the first I ever found, which after so many hours of playtime was hard for sure. Finally managed to find it tho, love when games troll you in ways like this.
Oh, and yes, you grab her tits, but she'll sigh and disapprove.
