Sorcerous Supernumeraries are sad-looking Denizen who failed their exams to become proper sorcerers and, under the rule of Superior Saturday, would never have had chance of getting a better post in the Upper House, during which time it was there duty to watch over the Grease Monkeys incase the Piper ever showed up.
Known Sorcerous Supernumeraries
- Doctor Scamandros (However, he left the Upper House, but was still technically a Supernumerary. However, after his promotion to Wednesday's Dusk it was cancelled.)
- Giac (He was persuaded by Suzy to release her from her bonds and join Arthur's company.)
- Aranj (She was with Giac guarding Suzy, but she was just sitting in the corner 'gone into a slough of despond'.)
