The Humana Cathedral Papers were a group of letters found outside of the Humana Cathedral of Spookiness. No one except for Barkjon, TurtleShroom, Explorer 767, Happyface141, and the South Pole Council have read them. Right after they were found, a skua boss stole the letters, but lost them while navigating the tall, forbidding spires of Humana Cathedral. The explorers who found the letters climbed up onto the roof to retrieve them. The letters were eventually locked deep away in a high-security vault beneath South Pole City. Mysteriously, the letters somehow got sent to Barkjon, TurtleShroom, and Explorer 767.
