Though I don't think it will help, you may check with the beginning of my story concerning Red Herring Puzzle Club.
It seems like it's been a long time since I tried to enter the R.H.P.C. As you may know, I lost a lot of reputation to find someone able to solve it, and moreover, when I was finally ready to give the answer, the bar I had visited had already been abandoned.
Yet I continued looking for any traces of Red Herring Puzzle Club. After a lot of snooping and sneaking all around the world, I found the bartender who gave me the puzzle in the first place.
-- Oh, Thomas, long time no see. Looks like you're a bit lost. But fear not, because today three suspicious people came to me and warned, that you might come by.
With these words he handed me an envelope.
-- I assure you, my friend, that inside you will find all the answers you will ever need. -- the bartender grinned.
After coming home (I already knew, I was never going to see this man again) I opened the envelope. There were 7 small sheets of paper inside. I have also discovered some diagrams on the outside of the envelope. Here is all of what I have got:
But, unlike the previous puzzle, this looks like nothing familiar. I don't know where to start at all! At least, I have unlimited time now, so I can wait for help all I want :D What is the mysterious message, hidden within these papers?
I should probably apply the transcript of two most informative squares:
piece 6, one way around:
??? (word was smudged beyond recognition) (5)
Panda (2) God (4)
piece 6, other way around:
Circle (3) Thus (2)
I will let your door be spun (5)
I'm a letter, not the start, (5)
I'm a smell that you should ban (4)
I'm with ocean in part one (6)
I'm before you'd say in Rome (4)
Canoeic palindrome, alas, (5)
I'm three less, if upside down (4)
I can swirl, flow, stick and foam (4)
And one of three who might be us (6)
I'm a distance you can run (7)
I am therefore from Descartes (4)
I pay taxes to no man (6)
As stated by OmegaCrypton, it's hard to distinguish green colour in the photos. Here is the 7th piece with all black numbers circled:
It looks like the same green ink was used on the cover, for the ticks and for a single dot.
A hint (a week has passed, 2 answers submitted)
A correction I couldn't have made due to the puzzle being on paper:
1) The "ABBACY" hint should technically be "ABBEY" (though I believe these words mean pretty much the same)
2) The "before you say in Rome" hint is completely false; not only I meant 'after', this word doesn't seem to mean even that (yeah); nevertheless, I'm not going to reveal it.
A special hint (on jafe's progress):
