I just found something in that thread that I discovered before and then forgot about, (at the time I was using "DefiniteInfinity"). But my post went relatively unnoticed so I'll talk about it again. Another link (specifically to the Halo Universe) is that another sword wielded by one of the people in the "Song of Roland" appears as an AI in the Halo universe. The AI and Sword are both known as [url=http://halofanon.wikia.com/wiki/Almace]Almace[/url]. You can read about Almace and the Archbishop Turpin's role in the "Song of Roland" [url=http://home.ix.netcom.com/~kyamazak/myth/roland/roland-items-e.htm#almace]here[/url]. Though I have not yet researched enough to figure out what specifically the relation between said sword and the AI in question, but it is definitely another link. Edit: And this could mean that there is also a lesser known and less prominent AI from Marathon that shares a name with one of the swords. Also, because there are a total of 6 named swords (and one spear) in the "Song of Roland", that would leave 2 remaining for the Destiny universe. Edit 2: I think that Hauteclaire might be the secondary AI (analogically, Hauteclaire is to Joyeuse as Alamce is to Cortana) in the Destiny Universe, as it was made at the same time as Joyeuse by the same cutler. Almost equally possibly could the secondary AI be Flamberge, as it was formed at the same time as Joyeuse and Hauteclaire. But, Flamberge is not one of the central "named" swords in the "Song of Roland" (Hauteclaire is) and is, in fact, a type of sword and not a specially made sword with a personified name. The fact that it isn't a "main" sword in the "Song of Roland" may not even matter, due to the fact that Cortain (Cortana) was not one of the main swords, but I think it seems likely that it will be one of them. Also lending credence to Flamberge not being one of the AI's in the next game, is that it, too was made for Charlemagne. On the Halo side of things, Almace and Cortain were made for two different people as they were completely unrelated to one another in the Halo story. Now, obviously, I'm beginning to hypothesize within hypotheses, but I've got nothing else to do. And... I could be entirely wrong and I could sound nothing short of a mad man. Meh.
