Mr. Mordaut

Mr. Mordaut is a dragon school teacher. He is seen during the Surprise Exam! random event. He is currently one of the only three non-attackable dragons in the game, the second one is seen briefly in the Recipe for Disaster quest, with the third being a 3 headed green dragon involved with the old tutorial, Learning the Ropes. The two possible tasks given during the Surprise Exam! are "Choose the next in line" and "hints". Once the player is done with all the questions, Mr. Mordaut will tell which of the four doors around the room to exit through. Upon completion of three questions, players receive a Random event gift, but instead of a Genie lamp, the player may receive a book of knowledge instead, which gives 50% more experience than the lamp. Mr. Mordaut is the one of the few dragons with the ability to speak and interact with other players aside from K'klik, the last of the Fairy dragons, and the King Black Dragon during the A Tail of Two Cats quest.

Trivia

 * When you enter the Mr. Mordaut random and you already have a Book of Knowledge, he will give you another reward. This was before the Random Event update.
