It may be mentioned in the videos but I always found it fascinating about a mysterious man that appeared and vanished.

I don't recall exactly when either during the creation or signing of Constitution or such.

It was a man in dark clothes appeared while the founding fathers or something were discussed America and the figure told them America was to be this or that.

Then vanished.

Wish I could remember details better.

But if he was some type of bad ass immortal type. Where is he now? We need someone like that.
