Welp anons, I think I've found who P finally is.

P means Pindar, or the "head" of the Rothschild family who is also the head of the Vatican.

The Pindar in their religion believes fully that he is a god among men who will "transcend" and pass the baton to his heir.

It used to be Guy de Rothschild but now may be Prince Phillip, which would explain the use of P instead of, I don't know, keystone or something else.

I always thought it was Payseurs, unless the Pindar is maybe intermixed with this batshit insane incestual bloodline and they choose the next P.

I did it guise.

Surprised I didn't think of it sooner given that the map here is a classic but fuck me I guess.
