Nope, not a clue. Apparently this is one of those strange time paradoxes that keep happening, where people come from different times and so forth. The guy came before he ever gave them to anyone else, so... it's anyone's guess at this point. Though if I had to take a wild wager, given who I think is part of the same world...

I could probably narrow it down to one of three people.
