I Keep Meaning To Finish Reading It But I Haven’t Even Though It’s Absolutely Fascinating - Blog Posts

La Tavola Ritonda is a cavalcade of different canons:

The Lady of the Lake, Sister of Morgan and, by extention, Arthur's

Lancelot stealing from Perceval's backstory

The Split-Shield from Lancelot-Grail, given by the Lady of the Lake symbolizing Lancelot and Guinevere's sexual union, being retconned into another plot by Morgan

King Pelles being King of Organia (Orkney). Also, Amite/Elaine/Pervida's Mom* organizing the... "conception"

*(It's kind of funny, but I've always felt that Brisen and the "Queen of the Wastelands" being separate characters was pointless) *(King Pelles x Queen Brisen, woot)

Uther Pendragon is Morgan's dad**

**(per the original Prose Tristan, apparently)

The events of Pulzella Gaia/The Merry Maiden being canon here. Yes, this technically means... a whole bunch of things

and finally, Lancelot has a daughter***

***(I would sincerely like this to be Gwen's but I'm not holding my breath)
