I'm okay with some of the grimoire cards that aren't really relevant to the plot of the game, and are only side notes, but it would be cool if they made a sort of archive-like library in-game that has all the uneccesary grimoire where you can maybe look up some of the exotics and get more info. Or look at reports from the field. That would be awesome. Maybe if it isn't already being used, bungie could make the library behind the circle door across from the speaker.
