inb4 you are a Guardian from the future sent to the past by the Vex in an attempt to destroy the Traveller but are misled by the Speaker who insists you must destroy the Darkness because the Speaker and Traveller know who/what you are. The fact that Crow should've existed and is suppose to shed "light" (pun intended) on how the Traveller and Speaker had brought the darkness could've led more of an interesting story.
