Probably shot myself in the foot here, seeing as I wasn't intending to do the Hermaeus Mora quest anyway, I started fussing with trying to get this done, and added the attunement sphere to my inventory, which got me partway to where I needed to go, but it wasn't until I was in the Tower of Mzark that I realized I needed a blank lexicon. So of course I just blithely added one to my inventory.
The Lexicon stand won't take it. I hit E and nothing happens. Concerned, I looked it up, and I can't find a solution, but I also discovered it crosses partway with a quest far ahead of where I am in the main quest... Did I just screw myself over? I hope not!
What do I do? I need the Elder Scroll to advance myself in the Dawnguard questline.
Do I have to go back through my saves (thus ruining my ability to get back to Blackreach easily) to remove both items, and then visit Septimus Signus anyway? (can I visit him anyway and see what that does?) Do I need to leave Blackreach and go back? (If only it was possible to tell Serana to buzz off for a bit, her wandering in circles asking me if I know what I'm doing when I clearly don't is wearing on my last nerve lol), do I need to go into the College of Winterhold and talk to the orc and THEN go back? Something else?
Help? Please? Thanks in advance.
p.s. I also tried the setstage console code, but that just gave me the quest to find it, and nothing else, and no marker. But I have a save right before it, so it's not a big deal to reload without that.
