I haven't rolled for your book yet, but I just wanted to drop this note in here so this question doesn't hang up any potential threads.

The only books that will require rolls are ones that are lore specific. If characters just want to grab books with general information, they are welcome to do so! (Books are of negligible cost in sand so let the curiosity roam free.)

If Ocelot unlocks a significant number of books I would just stick it in your Committed Actions somewhere. I hope he enjoys being the best dad. 🌺
