Suganerk told you that Jaiorunerk's Diary contained the secret cube crafting methods of a legendary cube craftsman, Vindachinerk. The diary went missing when Krall attacked Orton Farm. He asked you to find it for him so he could spread the cube crafting methods to others. After you found Jaiorunerk's Diary inside the stomach of Jaku the Glutton, you wondered who you should deliver the diary to.
