so I was thinking the traveler has been to a bunch of worlds, including the fallen's homeworld, even making the fallen guardians, but every time the "darkness" showed up it ran away. in the story it said that the traveler protected us from the darkness...what if it was crippled trying to run away so its only choice was to help us? what does it get out of helping us? it was hinted at that we are "food" for the traveler, maybe something like how either is for the fallen, as long as we use the light and fight and die for it maybe we generate some type of food for it? maybe its like the hive that need "destruction" to live. We sure do seem to do alot of killing and murdering not just to protect our self's but the traveler. Calus does hit at something "stronger than the light" and it does feel like he is trying to recruit guardians and there was a rumor about a 4th "darkness" subclass coming up.
