After this last clue (clue 8), I received a few inquiries on the Key. Searchers wanted to know if what they had deduced for the Key was the intended Key. In efforts to have this solved, I told them yes or no. I will do that for everyone.
So the Q/A is:
Q) If told the Key would you confirm or deny it?
A) Yes (as long as they are deemed not 'guesses' and are deemed actual attempts to solving by following the clues on the Scroll)
Can anyone who has found the key confirm whether or not it is the clues in the center section of the wings that point to it. Won't particularly help because that is where I am looking (and failing) but it may keep me focused.
