I think he's a mix of Sword in the Stone Arthur, Mickey, and Yen Sid, but he doesn't need to be anyone from Arthurian legend, because he's not.

Plus, he's thousands of years old and such. I'm certain they will name him in that episode or they'll never name him. Just will have to wait for the press release.
