Alright everyone go and watch the beginning cutscene of Destiny 2 for this whole thing to make sense .The cutscene seemed Normal right? No it is was not. In the the very LAST cutscene we see a mysterious alien force OUTSIDE of our galaxy, their ships were in forms of triangles. Still with me? Ok, back in the 1st cutscene, we see that the traveler gets shadowed By a TRIANGLE shape. As that HAPPENS, the Narator Says "An ancient enemy persued the traveler across the UNIVERSE" The darkness is Something/Entity! SEE FOR YOUR SELF!! All Credit Go's to: DRAGONCLAW47
