Brief History and Analysis (putting these together since this isn’t really a story): Arthurian legend can be hard as it’s essentially a form of mythology all of its own. The stories change based upon the region, the century, and whether the person telling the story was more supportive old British religions or Christianity. Still, I’ll try to make this explanation of this character as brief as possible. To begin with, she had different names early on like Anna and Belisent, but over time the stories gave her names closer to that of her sister, Morgan le Fay. Wait? What (those of you who didn’t watch Merlin or read Mists of Avalon are probably saying). Yep, King Arthur had two half-sisters and over time their stories were combined and re-written to try and make the legends less confusing. Morgan was usually the sorceress, the one who followed Merlin’s teachings and was constantly capturing the knights she had crushes on. She was really about destroying Camelot or her half-brother. She was just a powerful and selfish woman. Morguase was the power hungry, revenge seeking, mother of Mordred. She also learned from Merlin in some stories, but she is always the manipulative one and Morgan is the naive one. Mordred isn’t always Arthur’s son. In some stories he’s simply Morguage’s son that she raised to try for the thrown. Morgan le Fay practices black magic in many stories, but it’s this is about her personal gain and having the medieval equivalent of “sorry not sorry”.
Blame it on the Victorians: Victorian and 19th Century Arthurian stories and novels were the start of writing out Morguase and focusing on Morgan le Fay. The trouble was that no one could decide whether she should be evil or good. Tennyson made her helpful. Twain made her wicked. She was simplified over centuries into a side character or the villain of all villains.
Final Thoughts: Okay, I have a confession. I never finished watching Merlin. I just knew Morguase was a character on the show.
