We all want a somewhat comprehensible story in Destiny right? And we don't want to have to disconnect from the game to look a grimoire right? Maybe not in this game but for Destiny 2 we have a record book that holds our grimoire. We all have those times where we fly to the tower with nothing to do, do why not read some grimoire? It would be a bit like the codex from mass affect. Also a good in game story would be nice.
