Moisened Bint I believe was her name…

Post Roman Rule Briton.

Don’t get tied up in the ethnicity, that’s, for one thing, not really how they thought back then.

When Rome left Britain the power vacuum left a lot of warlords fighting for control of their holdings among themselves and against Sea Germans/Frisians who had also contributed to the Roman collapse in the first place.

Arthur is an amalgamation of folk stories from that time pressed into a cohesive whole through the growing tradition of courtly romances as Europe began to adopt notions of chivalry and knighthood among the ruling class.

He is, basically, a revisionist image of an England that simply never was, spread as form of early nationalist myth building. Among other things, knights weren’t even a real thing in the period he would have occupied. Not that there weren’t wealthy noble-class warriors with armor and weapons, but it simply wasn’t a system in the way it is portrayed in the popular Arthurian cycles, that developed in the Crusade era.

It would have had more in common with what you would think of as the barbarian tribes that fought Rome itself. Yes, there would be ruling class warriors with exceptional gear, but they’re not knights, that is actually a pretty specific set of conditions.

Fictional.

Brythonnic.

“Post-Roman Briton” sounds like “Post Malone, American” moved.
