Originally, I thought Merlin, Lancelot, Guinevere, Morgan le Fay and Mordred were the only people who knew Arturia was female when she was king.

While reading up on Kay's profile on the Wikia, I read that he knew she was a female and vowed to keep it a secret

Her identity as being female was known to him, but he kept the secret all his life after being sworn to secrecy by Merlin.

So this got me wondering: Was there anyone else who knew that King Arturia was in fact a woman? How did they find out?

  • They found out because it was obvious

  • Yes, pretty much anyone with a brain could've figured it out - however, the majority of people had to stay in the dark because plot Aug 15, 2015 at 23:58
  • Likely only Merlin, Morgan le Fay, and Guinevere.

  • Bedivere and Kay knew because they raised Arturia. Jan 8, 2017 at 5:19
  • @Xavon_Wrentaile Bedivere did not raise Artoria.

According to Garden of Avalon, only Merlin, Uther (before he died), Ector (her foster father that raised her from the age of 5), Kay (her foster brother), and Guinevere once they married. Closer to the end of Artoria's kingdom, Guinevere reveals this to Lancelot as well once they start getting closer.

In the Camelot chapter in Fate/Grand Order, Agravain reveals that he found out about it when he discovered the affair.

While not explicitly stated anywhere I'm aware of, the circumstances of Mordred's conception/raising imply Morgan must have known as well.


I think that after Lancelot and Guinevere fell in love, Morgan le Fay told everyone that Artoria is a girl.I'm not sure,but you could check the Type Moon wikia
