lol, I've found hills but no desert anywhere nearby. I even took my new Boots of the Traveler (with Haste 2) for a spin the other day and ran in one direction for three Minecraft days with no luck. Time to check the other directions. It was a fun trip, though, those boots are damn fast.I'm very close to having all the pages. Had great luck finding those page shrines in desert and hills biomes.
Update: Found a desert next to a Mystcraft villager and hut last night. The mystcraft library had a "single biome" page, and the villager sold me an alpine biome page for 5 emeralds. His next trade is a gold ore page for the low low price of 56 emeralds. Guess I'll be trading a bit before getting the next one.
