I'm an Arthurian lit fanatic and had a couple of questions. Dame Ragnal is implicitly Peredur's mother (her story is one of my all time favorites, BTW). In your world is Ragnal human? Her loathley appearance could be a curse, or she could be a child of Oberon or even a gargoyle based on her appearance in the old story.
In the story of Sir Gawain, his son is named Sir Gyngalyn. I'm curious why you gave him the name Peredur instead. Are these two names for the same character?
I am also curious what other Arthurian characters might exist (though that may be a spoiler). I'd be very interested to see what you'd do with Galahad, Lancelot, or Morgan LeFey.
In my reading, particularly in Roger Lancelyn Green, it's strongly implied that Ragnal is the mother of Percival.
Beyond that, all the rest of your questions are Spoiler requests. Sorry.
