(Yes I know I should've put this out yesterday)

The first Saber we meet in the Fate series, the blue Saber, Arturia Pendragon, better known as King Arthur. Yes, King Arthur has a vag according to Fate. Artoria isn't the most powerful Saber, but they're definitely not someone you wanna fight unprepared. They of course have Excalibur but with a catch. They have Invisible Air which makes Excalibur invisible, cause if someone were to see the glowing golden sword, it would probably be assumed to be Excalibur. Artoria is pretty cool and fighting an opponent with an invisible weapon would be pretty hard. Her personality makes her a little stale, but otherwise she's fine.
