So I was reading though the Book of Sorrows and some other Grimoire stuff and hit upon a wild theory. Oryx's "God" for lack of a better word was an entity named Akka, one of the worms. Oryx killed Akka and took the power to make the taken via harnessing the "Deep" from one of Akka's pieces. This is how Oryx became the taken king, at least as far as I've gathered. So this means that Akka previously held the power to create the taken. And somewhere in the Book of Sorrows it says Akka is dead but far from gone. Now on to Xur. He says himself that his will is not his own, and that he cannot endure the presence of light for a substantial amount of time. Also he notes that his body descended from earth, but this distinction could mean that his mind, or his will, does not. And ever since I started playing the taken king I noticed a weird similarity: Xur's tendrils look somewhat similar to a taken's, but severely diminished or burnt out, possibly because, as Xur says himself, he is dying. Another conclusion that can be arrived at is that is Xur is indeed a taken, possibly a taken guardian (which would somewhat explain his ability to go wherever he wants on the Tower without the Vanguard being able to stop him), who created him? Oryx never came to the Sol system before the Taken War, so who else has the power to create taken? Akka This is where the Nine come in. In one of the Grimoire cards, one of the possible origins of the nine is: The Nine are the shadows left by the annihilation of a transcendent shape, burned into the weft of what is. There is a lot of shape imagery in the lore of Oryx and Akka's species, the Worms. Could these shadows that make up the nine be the remnants of the "shape" of Akka? it certainly doesn't sound impossible. Oryx didn't make every piece of Akka he cut up into one of his tablets, so maybe some survived and followed the Traveler on their own, eventually reaching here. We know they knew of Oryx's coming, because they told Skolas he would come. Why would they know that? Because they are Akka, and if Oryx still uses shards of Akka to derive his power, they would feel those shards approaching. It would certainly explain... well absolutely nothing really, except possibly how the Nine knew of Oryx's arrival before Eris or the Queen. And maybe it would explain Xur's strange appearance. Or maybe I'm just reading too deep into things. What does everyone else think?
