I feel like the traveler isnt as good as the beta made it seem. It could be trying to enslave the human race by giving it gifts and protection so they come to rely on it. Also, anyone else think about if it is possible that the Fallen where the last race the traveler provided its protection to? Look at who they worship in the beta, it was a sphere that looked like the traveler but smaller and purpler. The darkness and the traveler are probably at war and both think they are the are doing what God or whatever intended them to do... They both feel they have manifest destiny. That hunter girl could be a Guardian who found out the truth about the traveler and the darkness. She could fight to establish a human race independent of both. For example when we found the ghost on the moon, it was filled with darkness....but the ghost came from the traveler didnt it? Shouldnt it of been able to either resist the darkness or crumbled under its might...The traveler and the darkness could be one in the same.....white in negative is black and black in negative is white
