The land layout changed a bit in the Edgeville dungeon. Chronozon no longer presides in the wilderness, but rather, exactly south of where he used to be. You don't follow the same path to get to him though. I also thought that in the explanation of what you need to do the quest, you should have that the Normal Magic spellbook is required. I happened to have Ancient Magik on at the time I tried that. Half way through the quest I had to go back to the pyramid to change to Normal Spellbooks, and when I finished, I had to go back to be in Ancients again. Just thought I'd mention these.

Thanks for bringing this to our attention, I have added a note to the quest guide about needing to be on the normal spellbook for the quest and I have also updated the dungeon image in the guide as well. The quest guide should be released soon.

Thanks again and if there are any problems feel free to pm me. :)
