I guess Bungie's way of telling a story is basically through hidden lore for us to uncover. No wonder we all collect and gather and say that's it? Thanx for taking time to put this together. Would have taken me a while to figure this out if not never. It never called me to really know what the touch really is. I just wondered every time I used it. Now it makes sense. To weaken Oryx we needed to use his power against him and finished him with the light of the travler.
