A bit nitpicky, buttt in older versions of the myth, Mordred was originally Arthur's cousin, later progressing to becoming the son of Arthur and his half-sister Morgause (whose commonly axed out of modern interpretations of the myths). Morgause became combined with the character of Morgan Le Fay, who was (also) Arthur and Morgause's half sister, to the modern day character of Morgana Le Fay. Mordred then became the son-newphew of Arthur and Morgana in popular culture. Again, this is like, a really random comment about something only tangentially related to what you just said, I just wanted to info dump bc the legends are genuinely very interesting. :>
No worries, I think it's great when people info dump stuff they're passionate about ^^ !! This is all very interesting to me since I've never thoroughly looked into the Arthurian legends, but because of your game, I am now interested in finding out more about them and the different versions of the stories, so thank you for getting me interested in something new, haha!
