I think I have solved the riddle of the Arthurian survivors:
1. King Arthur (Obviously)
2. Merlin (Imprisoned in the Crystal Cave)
3. Nimue (Trapped with Merlin)
4. The Lady of the Lake (A faerie)
5. Perceval (Heir of the Fisher King and thus preserved by the Grail)
6. Blanchefleur (Same extended to Perceval's wife)
7. Morgan le Fay (Preserved by her magic)
8. Queen Mab (Usurped by her son Oberon but imprisoned somewhere on Avalon)

The last is the uncertainty. You have already stated that she exists in the Gargoyles Universe but I have been wracking my brain to remember if she was an Arthurian character. I know she was a figure of British mythology and was in a great many poems (The Faerie Queene, Le Belle Dame Sans Merci) but her connection to Arthur is tenuous. So how about it? Have I guessed right?
