...a little research into Cortana's name gives a bit of legend about Charlemagne. That's right. Charlemagne. Particularly, this legend where Charlemagne presents a sword to the prince of the Danes.
The sword bears an inscription:
"My name is Cortana, of the same steel and temper as Joyeuse and Durindana."
And of course, the most famous of the Princes of the Danes was ... Beowulf! †Another AI in the Fall of Reach!
