Cornelius Mazurka once conducted a "seventy-five-piece consort of brassmen and hadros" in Ruhmsburg. He lives in a partially collapsed tower of the ruined bridge over the Jubila River. He remained among the ruins living a hermit's existence, along with his dinosaur partner Henriette, after most citizens fled from the city. He maintains a collection of antique instruments, though no one plays them but himself. Arthur Denison and Bix convince him to pack up his instrument collection and leave the city so he can start again. [1]
