It has to be possible to place grimoires into the game. It would be wonderful to have them somewhere in your menu where you could listen to them (audiolog) to know more about the story. I have really no love for coming and seeing them on bungie.net and I assume many players feel the same. Voicing the grimoires would help a lot to get to know the world and history. Also, for the kill a certain number of each enemy grimoires you could split the story in sections and we would gain a section of the story every time we hit a certain number of kills.
