That vid was sick, props to whoever made it. I too have had a somewhat similar theory, though not as well thought out. What if it is not The Traveler, who demands the sacrifice of our own, but instead one of us? For centuries and millennia, we have deceived one another, destroyed each other, all for the sake of gaining something. That something has been many things, land, race...knowledge. We have to remember that the belief back in those ancient times, that knowledge is power, still hold true today and The Traveler is nothing but knowledge, who would stand to gain the most from this? Could someone be taking advantage of The Traveler's weakened state to study it further, draw out its knowledge, it's power? I do not wish to point a finger, lest three more be pointed back at me, but I believe it to be someone in The Tower and each day their knowledge grows.
