I wish it were more than just text. Some of the grimoire cards are ghost fragments from the golden age or other guardians findings. I remember one I found was about one of the original astronauts who landed on Mars and first encountered the Traveler. I would love to see fragments of video footage for such a thing. News reels, newspapers, holograms of other guardians discussing findings or tales of woe. Just more immersive stuff than text. That said, I'm obsessed with finding as many grimoire cards as possible and pouring of the lore.
