So, after finishing what was a near non existent narrative... [spoiler] really don't understand the stranger, a random female Exo that shows up, tells you where to go to advance the plot, gives you no reason to trust her, and then leaves! I had a theory, that she's possibly the manifestation of the traveller, as she claims not to be a guardian, knows how to cripple the darkness, and teleports into a white like material, even at the end she teleports, straight in the travellers direction. [/spoiler] Thoughts? Counter theories? Right now she's just a cheap exposition device.
