I was watching full metal alchemist,and they used a term which I had not searched for yet. "The grand arcanum" Upon looking it up I found the usual FMA fandoms but I also found something else very exciting.
There is another forum much like this one used to be. It has a charismatic leader who seeks alchemists who are already "in the know". And there are a few pictures of a red liquid very much like the one Nick had.

My gut instinct tells me that this guy has the stone,but it would be very difficult to earn his trust well enough to obtain it.
