Actually I am reading the Darth Plaguias book and according the the author.
Palps was also conceived by the force because his father said. "you werent my son"
So did the darkside of the force coceive 2 children through the method described in Episode 1?
How does a father saying someone isn't his son automatically jump to that? It could imply an affair by his wife, or just the way he acts is as if he's not his son. I wouldn't take that he was born from the force at all from that.
