A member of the powerful Lavish banking family and son of the late Sir Joshua Lavish. He is obsessed with Lord Vetinari to an unhealthy degree, imitating the Patrician's mannerisms, clothing, and eventually acquiring a replica of Vetinari's signet ring - which begins to poison him. He schemes to gain full control of the Royal Bank of Ankh-Morpork and views Moist von Lipwig as an obstacle to be removed.
