I was just wondering about the incidences of the number 72. Is that all co-incidence or sumthin' else. Couldn't dere be any other number? And what bout' the P.o.E.? What material are dey made up of? What thing gives dem so much power? And why did Ezio chose the number 72? Were Those Who Came Before native to earth or dey were sum sort of aliens who setteled on earth?
