So I'm new to this site but I see that you guys seem to know what you're talking about. I have lots of things I'd like to ask but I'll start with the one that interests me. Obviously we all know that King Arthur is not a real person, essentially the British people's equivalent of a Charlemagne-esque figure since a real life one didn't exist as far as I know. So who exactly is King Arthur based on? Is it multiple people in one? Or is it actually just completely fabricated?
