Gregorius, the Chosen One.

“Puppeteer, tell us a story we don’t know yet!” the audience calls out to a traveling thespian. And so he starts to recount a story about a boy born of the forbidden love between brother and sister, who had many adventures, who spent 17 years tied to a rock, and who perhaps was also… a hedgehog? But that’s not as important as how, after overcoming all these obstacles, he ended up becoming the Pope.
