Hmm, it doesn't actually say the fur is brown. I honestly have no idea where I got the word brown from at all in that case, apologies for getting ahead of myself.
But at the same time, the other evidence matches up well enough. So I'm almost certain that the culprit in question is still Golgari, my vote still stands.
After all the quote still mentions that the fur is useless and leaves the question after it. "Maybe that's the point?" To be honest, if the fur was pointed out as being specifically brown it might be a little too obvious. None of the roles have anything to do with fur specifically... and no other members have any mention of any sort of animal or fur in their usernames apart from Absol.
However I'm still sticking to Doof, because he purposefully chose to search the same location as somebody else, even though it was nothing but a drawback to do so.
Look at the statistics anyway, most people have searched locations I suggested and all but one of the clues have been found. If I was just misleading you, why would I have made such a detailed description of the most likely places to find the clues.
Especially when i was right about it.
Nobody but Ryo and Nagi knew how the clues worked, how obvious they'd be or what they would even do for us. So why would I make such an outlet that if correct would leave me out to dry. That would be incredibly stupid.
So my vote still stands, colour or no, I'm fairly convinced that Golgari is Despair and to be honest, there's nothing to say that he isn't... or to incriminate someone else more so than he.
