Interesting to say the least. It also kind of fits with my theory that the Traveler is part of the Vex as i surmise that only a Vex Overmind (Judge) could stop the Vex cold from transforming a planet.You need to remember that the Vex are a Darkness so Dark they despise all other Darkness. That can only happen if the Vex were so seeped in the Light that they didn't have a concept of Darkness until they encountered Crota. And Because they had no concept of Darkness the Heart of Darkness was able to corrupt the Vex so compleatly. I would like your thought on this avenue of thought and also why you think the Traveler choses us the youngest of all the races to be it's last defenders of the Light.
