Merlight

Merlight was one of the four great sages of the Tribe of Ancients, spoken of during the events of Super Paper Mario. Tippi reveals that he was knowledgeable in the field of the worlds and was responsible for the design of Flipside. (It is unknown who designed Flopside, although its creation was indeed another feat of the Ancients.) He is distantly related to Merlon, who looks identical to him and apparently possesses a large amount of the books he left behind. (Interestingly, however, the angular positioning of his hood in the stained glass window of Mirror Hall he is seen in actually makes him appear somewhat similar to the Merlon of Paper Mario: The Thousand-Year Door, though this is thought to be a coincidence.)
