I wouldn't have known that from the story. Read the spoiler for what I would say here.

I did. You just asked "Who? Where?" and I didn't see a full explanation.. At least on the "who".

My point is that they can make a really cool story with all this lore but they didn't involve enough of it in the main story. Someone in my living space is keeping up with the game so I will get to keep playing the content without buying it. I see the potential that but has with this story and because it is still there I will more or less stick around to see it out. Bungie can do it and I hope that they do.
