User blog comment:Morganaforever/Are Arthur and Morgana siblings after all?/@comment-5102537-20120604155329

As I understand the whole conceiving thing about Arthur, Nimeuh helped Igraine to conceive but for that, a male counterpart is always necessary. I mean, it's not exactly like Jesus was conceived out of nowhere, which is only metaphorical anyway.. Magic helped Igraine to be capable of conceiving the natural way, like in our real world medical science can help women or men who can't procreate without help due to infertility. So magic replaced our medical help, so to speak and the only magic that was done was making Igraine fertile.

Otherwise, Arthur would have no father and the Old Religion itself created Arthur, which would make Arthur being a magical creature. He is only a normal human being, and I am sure he was conceived the natural and biological way after Nimueh "healed" Igraine. I can't believe that Igraine and Uther didn't have any sex after Nimueh was asked for help.
