I'm sure everyone has heard this already, but I just now listened and I gotta say it hits you right in the feels. With everything we know about the story of Destiny 2, the theme is pretty epic. From this 3 minutes, I imagine that some one important dies near the start, we turn and see the carnage and the traveler, we escape to the wilds and see it open up before us, we then counter attack the cabal in a race for time. https://youtu.be/PrsIjWFds00
