Runnet was an apprentice in the School of Mist during the events of The Curse of the Gloamglozer. He was unprepared for an important examination, and desperate to pass, for fear of being expelled and disowned by his Leaguesman father. He was seen trying to buy a copy of the paper from Skillix, and, after failing at that, was offered the answers by the Sub-Dean of the School of Mist, Seftus Leprix, in return for thirty-eight gold pieces and assistance in turning a mob of academics against Linius Pallitax.
