Department of Redundancy Department
The Department of Redundancy Department, (PROSE: The Crew of the Copper-Colored Cupids) or Department of Redundancy Departments, (PROSE: Magic Trick) was one of the Departments of the Crew of the Copper-Colored Cupids's Intelligence Institute. (PROSE: The Crew of the Copper-Colored Cupids)
Its Prefect was Recursion-462. On the day of the faceless magician incident, he had been participating in the Cupid Parliament's protracted debate on whose responsibility it was to refill the ink in Stenographer-123, opining “It’s obviously a job for the Department of Documentation, whom it is obviously a job for!”. When the argument briefly devolved into a fistfight, he was attacked by Technophile-963. However, the scuffle didn't last long before the onslaught of magic rabbits forced the Cupids to evacuate the Cupid Parliament building, with their destruction of the typewriter rendering the earlier fight moot anyway.
