This is interesting... Maybe I can get my feet wet into a group RP with this...? I've got an idea for a psychic priest in the Vatican, who is a close friend of the Pope (a fictionalised version of Benedict XVI perhaps?). He is at some point elevated to Cardinal (initially kept as a cardinal in pectore by the Pope), and should be elected the last Pope just after the Apocalypse begins. There is the Prophecy of the Popes
, and it holds that Benedict XVI is supposed to be the last pope before the Apocalypse ("Glory of the Olive"), and his successor, the final pope, is supposed to take the title: "Peter the Roman, who will pasture his sheep in many tribulations, and when these things are finished, the city of seven hills will be destroyed, and the dreadful judge will judge his people."
I'm working on a character sheet right now, and I hope that y'all think this is a promising idea.
