Ermehgersh... I can't remember which episode it was that this happened but this show annoyed me haha.
When I first saw it, I guessed that Saber was Joan of Arc. I mean, that makes the most sense doesn't it? I can't think of many other heroines of lore that are like Saber besides Joan of Arc, and the saber is a European sword, so I figured it could be kind of a French thing or whatever.
Then again, I guess Joan of Arc wouldn't have "an obligation left unfulfilled" that I can think of.
But no, this couldn't make sense for Saber, being a woman, to be a personality who was historically female. She had to be some feminist King Arthur wannabe!
The whole thing was pretty ridiculous to me and even though I loved the story I couldn't help but laugh when she or others called her/herself "a king."
King Arthur... a woman... honestly? lol
