Maybe it needs to be close to awaken it from it's resting place

Maybe but if the papyrus wouldn't show itself to anyone else, then how would people know the location of it's resting place?

Maybe F.O.W.L has already located it but they need a direct descendant of Scrooge so they made Webby. But before they bring Webby to the papyrus's resting place, Webby is stolen by Beakley

But how did they locate it?

That weird altar or whatever in the library seems to have been tied to the papyrus by some means.
