the authorian legend was created by a Frenchie anyways
For those interested in it, a certain Geoffrey of Monmouth is widely credited with promulgating the Authurion legend. his reason was to promote the Norman conquest as the final victory of the Britons against the hated Saxon invader. In that way the Normans sought to protect and cement their conquest by portraying it as the final chapter in a age long fight twixt the Saxon invader and the native Briton. Indeed a lot of William the Conquerors soldiers came from Brittany an area populated by the Britons following the Saxon takeover of England in the 700s.
