I went to one of the desert villages to trade with a librarian and a farmer today/this evening. To my utter delight the librarian upgraded and now sells an infinity enchantment book for the lowest prices I've seen of 10 emeralds. Woot :)
I took some pictures to show where the village is and I have a small cabin on the water there that you're all welcome to use. Coords are 7138.665, / 64 / 6316.503
