Minecraft wiki entry for 3CHP, associated text: Fin flings the book away from him in fright. The book slips out of the cage as it plummets to the ground below. Roary disenchants another book, which is shown to have the "Feather Falling" enchantment, but discovers Mo’s handwriting behind the instructions. Mo reads it, with it being very much identical to Fin’s handwriting, except she thinks that her twin is alive and says that she’ll see "El Fin" on the other side. The rest of the enchanted books are disenchanted, being in either Fin or Mo’s handwriting. They are basically identical, except that some events were different and some names had changed. The group then begin to wonder who "Ultimo" and "El Fin" are. Mo confesses that the ender dragon called her "Ultimo". Koal then mentions that "Ultimo" could refer to "Supreme Brewmaster Ultimo". Roary follows up that "El Fin" could refer to "El Fin the Archmage". The group then hears a commotion down below, noticing Jax among several wounded endermen.
