Perplexus Anomalous is an Italian peculiar cartographer who is most known for creating the Map of Days, a collection of maps that show the location of every loop throughout the Peculiardom. Not only was he a cartographer, but also a philosopher, and great thinker, as Millard admires him greatly. Perplexus Anomalous's name is on the hard cover addition of Hollow City.
