The Anur System is a dark and gloomy planetary system in the Milky Way Galaxy, inhabited by species that mostly resemble classic Halloween monsters, including Ectonurites (ghosts), Loboans (werewolves), Thep Khufans (mummies), Transylians (Frankenstein's Monster), and the now extinct Vladats.

Very few beings have any contact with the Anur System, including the Plumbers -- an intergalactic law enforcement organization that protects the universe from various threats and attacks -- and the inhabitants of the Anur System often think of other species outside of their system as monsters, being frightened by their unnatural and "terrifying" appearance compared to what they're used to.
