Seftus Leprix was the sub-dean of the School of Mist during the events of The Curse of the Gloamglozer. He wished to become the Most High Academe of Sanctaphrax, and made multiple attempts on the life of the current High Academe, Linius Pallitax, with the assistance of his accomplice, Bagswill. One of his assassination attempts backfired on him when the poisoned Sapwine he gave to Tweezel to give to his master ended up being re-gifted back to him, and he died from the hover-worm venom he had put in the drink.
