Still has no basis on Arthur's legends, so it keeps on being baseless BS.

Indeed, but you do know that King Arthur is the blade's owner (doesn't mind if you lived in Japan, or the middle of the Pre-Colombian Americas, you know and respect Excalibur). Knowing that Arthur is in truth Arthuria is another thing, and the reason most get shocked at first, still it's the same thing in a way.
