After reading the wikipedia article relating to Charlemagne, and then moving onto Joyeuse; his personal sword, I've found some food for thought material. During the conquest of Lombardy, Charlemagne had made the magnates (people of a high social position in the society) pay homage to him. It was at this moment he was crowned with the [i]Iron crown of Lombardy[/i], given at the capital of the kingdom. With correlation to L00's post above, this crown was believed to be forged from one of the nails used in the most famous crucifixion in human history. A link between his sword, Joyeuse, and the crown if ever there was one. Given the crown made one a "A King of Italy", which embodied power, strength, and intelligence. L00's speculation about Joyeuse being an AI which has those delusions can carry on to the protagonist at some point within the game. Charlemagne possesses a "rampant" sword, which controls him through the "Iron crown of Lombardy"; or something along those lines. [Edited on 03.21.2012 5:52 AM PDT]
