Well, I spent a good amount of time searching the entire map available to me. I'm probably way off. The clue given is to look for something that GRABS you. Okay, so she does 'grab' me when I enter the twilight area where the bridge was, but this area is not very large and I've searched it. The only think that stuck out were two pillars in the gorge itself, but I have not been able to get to them. Any tips?
