I am trying to get the Bookworm Badge. It seems as though I have to complete Zan'ne quest. I have finished all the lands in the spiral. I am a level 50 and have all my badges except for finishing off some spiders, golems, undead, etc. Except I can not get the Bookworm Badge!!
I have gone back to the library in Kroktopia and the only thing that happens when I talk to Zan'ne is he wants to sell me treasure cards.
If I recall some of the book quests started because someone ELSE wanted a book. Hetch A'Din, the guy inside the spiral door room, and so on. I would recommend looking to see if any of them have a quest you missed. Also check for manders inside the pyramids. I believe the mander in the chamber of fire in the first pyramid is involved in the "history of the manders" quest at some point after you complete his first quest. Maybe you missed one quest somewhere. Also, there is a wikia about wizard 101 (www.wizard101.wikia.com) and it includes a complete list (as of this point) of all the quests for all the regions, including Krokotopia. You should read through them and see if you can find what you're missing.
