It's a rich concept. Not a story. Firefly had a good story. This grimoire would be like a character from the show, and a side character at that. Is it important? Yes. Good? Yes. But it isn't a story. Stories are told to us. Removing us from that and putting it in grimoire with nothing to tie them all together completely destroys the idea that this is a story. The lore can be VERY good. But Bungie -blam!-ed us.
