Something that confuses me is that we speak about the traveler as if its a living thing. But to me and I'm sure others see that's it's mechanical. So could there be a biological being controlling the traveler or could the traveler be a half bio/mech just like (you got it) the Vex. Of course if the traveler is half bio/mech then isn't it to much of a coincidence the vex are also the same? But if something is controlling the traveler then who or what is controlling it? What confuses me as well, they say the traveler is in deep slumber from sacrificing itself, so how is it creating ghosts? Did it create the ghosts before it started his sleep and is it still making them? As we know as well we find dead ghosts in the game. I'm very much looking forward to the climax of this game (if it has one).
