So, I was playing my nice new king of Britanny, his father happened to be a saint but the pope disliked him (something related to his gluttony and his short reign and lack of piety). So, while I put away my chancellor to fabricate a totally (il)legitimate claim, the pope excommunicated me. It also happened to his dear ather, but he then become paragon of virtue. I chose a different path for that one... Since I had free investiture, I decided to create an antipope. It has been some years nowand I wonder how I could mend the schism I created. I there anyway other than invading and sacking Rome?
