To be completely honest, and I really HAVE been generally paying attention the game, I didn't know what the hell the grimiore was until just in the past 30 minutes lurking the forums. I don't feel silly though, as Bungie definitely didn't make MANY things clear for us for both in the story and other things. As for addressing the topic, I understand there will be lots of DLC and such in the future. But they honestly could of at least worked on the story. Given more insight onto the hunter-chick who was forged from the light, or why your enemies are fighting other enemies. Putting this kind of info in future DLC I GUESS seems like a good idea, but it seems as if a lot of Bungies Destiny players are realizing how empty they feel on the storyline. The voice acting for the Ghost, however, isn't supposed to be super multi-toned. It IS a machine, to be fair. It has it's own personality and humor, but Bungie (in my opinion), did a good job of reminding us that the ghost ISNT human, which is why it's very monotoned. Voice acting for other characters though is meh. Guardians VA is okay at some parts, but they definitely could of had them show more emotion. Each species DOES have the background to show emotions or feelings, maybe even the exos. All this monotone bothers me a lot b
