Iconographer (photographer) for protagonist William de Worde's Ankh-Morpork Times, Otto uses regular and dark light to capture images. Otto answers a help-wanted ad in the Times and is hired after making clear that he has taken the Uberwald Temperance Movement pledge never again to drink human blood or the "b-vord" as he refers to it. Otto is thin and pale-faced, dresses in black, wears dark oval glasses. He clutches a twist of black cloth as a talisman. He speaks in an Uberwaldian accent, a generic and inconsistent Balkan patois. Several times shocks to his system nearly make Otto revert. His Times colleagues, however, restrain him and sing temperance songs while bloody non-human meat is found to satiate him.
