There's always that difference between sticking to the facts and trying to connect dots. After what I've seen, I think (for those that want to explore the story) Bungie purposefully leaves breadcrumbs to be followed. Anonpig has been temporarily banned in the past for what he's revealed after studying the grimoire, so there are right answers to be found. But for you, one who prefers to wait for the facts (which is different, not worse), you're going to have problems with posts from our ruinous Tree and Anonpig.
