I think it would be interesting if there were Earth quests. KI hinted that your wizard was from Earth at the beginning befrore the test and during the Selena Gomez thingie. No other wizard would know what was going on exept for you. The story would go something like this; strange magical forces have been resonating from a planet very far out of the spiral and Merle wants you to investigate. Once you get there you get ambushed by mysterious creatures. after defeating them you go off to figure out what they were. i think KI would make a really awesome world based on earth. Just food for thought.
