I don't even have time to explain why I don't have time to explain how many times this topic has already probably been covered. But I came to this realization, and this idea, and theory. Now I know what you are all saying... You're not saying, you're sighing. "Theory? uhg." The traveler is associated with the light. And he brought his light upon the many civilizations he has come across, bringing upon each, a golden age. But each of these civilizations encounter a collapse at then end of this golden age. After this collapse, the traveler moves on. What of there is irony in the light. How have the guardians not seen this, realized that with ever golden age the traveler has brough, it has been met with a collapse. Has the light of the traveler had no other purpose than to blind them, blind them to its past transgressions it's brough upon the past civilizations and planets it's come across. You're ghost says that the traveler used the last of it's light to create the ghosts. While the traveler lies dormant, there is no light to blind them. These ghosts, "The exo stranger" refers to yours as "Little light." What better way to keep you blind than give you each your own companion, one that seeks out guardians... Guardians! and revives them. They protect the traveler while it lies dormant. Almost like an immune system. So what if the lights purpose has been nothing more than to blind them guardians into guarding this traveler well, blindly. What if the darkness is merely those who have witnessed the traveler's wake of destruction. You fight the darkness, but do you really know why, other than "they're evil, they're the bad guys." That's all I have for now, so I will go, and leave this here.
