Everyone, I give you the Scottish Immaculate conception!
In my Scottish game I immediately got the Joan of Arc event chain (one of my favs) and my king, inspired by one of his courtiers became celibate. Not a problem as his wife had already born him 3 sons. Then his wife died and he remarried the fair maiden and military genius Orabilia. They lived happily and platonically for a few years until the kings first born fell to pneumonia at the tender age of 16. Then overcome with grief the king fell to lust and the following happened ... or it was the immaculate conception.
My celibate king:
My celibate queen:
The result:
I'm really, really tempted to name the child Jesus lol. I will post his stats shortly, I just paused to share this story and odd event. I always love the Joan of Arc event chain, usually marry her and have always wanted to have a child with each version of Joan

... finally my Scottish King succeeded were all others failed.
