The Demon Realm

Civilization Summary
The Demon Realm is the predominant realm of the demonic forces of The Demon Lord. The scenery of the monster realm, with its ever-somber black earth that is illuminated by plants that glow blue and purple, and works of art that incite lust in humans and monsters and guide them towards intercourse may appear sinister or obscene to the human eye at times. However, the environment of the monster realm which is even called “a world for monsters” is very comfortable, and an easy place to live for all monsters and the “incubi”, human men who were showered in demonic energy after having sex with monsters and changed into an existence that is more convenient for a monster's husband.
