In a place where there's tension between the monarchy and it's people, lies an Academy that helps educate many into becoming Knights, ninjas, spies, ladies in waiting, medics, and more. One day, come foreigners. Soon after their arrival, children start to disappear, more riots within towns erupt, and more threats arise. Can the characters find out if there is a mole in the academy and who is at fault? (Yes I know this is pretty cheesy)
