Theories

[b]Xúr [u]a theory[/u][/b] Xúr agent of the nine. Xúr is actually a worm or ahamakara. The Xúr we see in the tower is actually just a agent of Xúr while Xúr is a member of the nine. The reason I think this is because all the worms have one thing in common, a three letter name. The agent of the nine we see in the tower says a few things that support this theory. "My will is not my own" and then another thing he says is "It was my will to speak to you." The first saying is definitely the Xúr we see in the tower, and the second is from Xúr the ahamakara. As you see Xúr the ahamakara is speaking saying he wanted to come to the tower, while Xúr in the tower is not here because he wants to. Xúr the one we see in the tower is some alien species could be human, could be psion, or could be awoken mind controlled by the worm, as we see if you look at his face you see something that looks like the worm in Oryx's chest. Edit1: even more proof These are some quotes that I have heard Xúr say. 1: [b]"We came up from the dust, and burrowed into flesh for warmth, and became... something new."[/b] if that doesn't sound like a worm or ahamakara I don't know what does 2:[b]"There are no birds where I came from. The things that fly... are like shadows."[/b] this sounds like ahamakara. Like Xúr is saying that ahamakara are on his world.
