Okay, so I picked up Edwin while I was in an active romance with Anomen, and he bugged me about finding the Nether Scroll (typical/expected behaviour). Then I had CN Anomen kill his father, so he ran off, and I think that triggered the start of the Edwin romance.
Now when I try to get Edwin's nether scroll in the graveyard, he won't say anything, and I can't get the sarcophagus with the Lich to open. But if I dawdle and do other stuff, Edwin keeps nagging me about finding the scroll.
What the heck is going on?
