Could be. But...I'm trying to reverse engineer what we know and how it relates to the poem.
The stanzas through 5 relate to Key 1 which we pretty much all know. (Anyone new to this forum, just read the posts and you can figure out key 1).
Then we've got Stanza 6:
To find the second key
You need assistance from a man
Whose fortune came as a surprise
While clearing wood upon the land
This had us all stumped until Lukas' hint in conjunction with mini hunt #2 of "Go north 11 miles. There you will find the man who will help you."
The answer is James W. Marshall. Texttext was the first one to post this, but others also figured this out, and it's not too hard to eventually get there with the hint. Approx 11 miles north of the answer to mini hunt #2 is a status of Marshall, the only 'man' you can find in that general area. And then if you google who he is, it's a dead-on match.
So what is the assistance we need from him?
Lukas also gave us a hint that we need a book to get Key 2 (also mentioned on this forum).
Just days after the 11 mile hint, people started finding a webpage that contains cipher text. Findingthetruth mentioned it has numbers, commas, and hyphens which sounds like a book cipher to me. Probably where 'the book' comes in.
So how did they get to the ciphertext page?
We were all stuck until James W. Marshall.
The next stanza is 7, the one for this thread:
Then with your newfound knowledge
You must travel through black flame
The place where alchemy’s best is found
Will help you win this game
It must have something to do with Marshall since that was the catalyst that got at least 4 people I know of to a ciphertext page.
So my thinking is either:
A. You're right about Harry Potter and the meaning being that we have to enter something in backwards. Which would mean that something related to Marshall needs to be entered backwards. But...if that's the case, why wouldn't people think key 2 is this 'something?' What would make people go looking on the website for a page?
B. 'The place where alchemy's best is found' is his website and is an indication that we need to find a page. For example, in mini hunt #2 Lukas' "the gem that's hidden" was just a creative way of referring to the prize money. So the place where gold is found might just be a way of saying that digitalburiedtreasure.com is needed.
This begs the question, what is "your newfound knowledge?" Is it the name of James W. Marshall? If so, traveling through black flame might related to him. I was thinking maybe it has something to do with the black smith shop that is part of the same park.
Or is it the book that we need? Is it related to Marshall? to Black Flame? To Harry Potter? And how would we know that we need a book without his hint? I guess just from the format of the ciphertext.
Anyway, Marshall is the key because once people figured him out, they started stumbling on the ciphertext. So I think that's the place to work out from.
