You pull out the older of the two books. As in, you pull out the one that has spent the most time out and about, existing. Terminology surrounding books of the same existence is very strange. One book can be called both young and old, and the other more novel. Puns aside, you pull out your writing utensil of choice, NEWTON'S FLAMING LAZER SWORD. The ink which flows from it is immeasurable. You used to write with it and use it as your primary weapon before you had been issued the 6 of Hearts and then you swapped it for your ACE OF CLUBS. You carry both now in your weapons slot, which makes it seem a bit crowded.
You see, the pun there is that pens are mightier than the sword, and NEWTON'S FLAMING LASER SWORD is a philosophical razor that says that if a statement can't be proven by observation or experiment, then it shouldn't be discussed. I only chose the FLAMING LASER SWORD because it sounded cool, and the other exiles got to have weapons based on philosophical razors. And it is a real razor, I didn't make it up for this comic. You can look up newton's flaming laser sword on the internet, or look for Alder's razor.
You draw a recreation of the alphabet in the book and go to type in the information for SENDIFICATION.
