Hell (or the underworld) is the magical realm below the Earth and home of all demons. It also serves as the afterlife for deceased mortals who committed many sins in life. Luci often recalled how he and other demons punished and tortured damned souls in Hell. In Hell, it is often said that hope's for dopes, likely because the place is hopeless and so is escape.
Since Hell is a tangible location, it can be accessed from the surface world, and it is possible for living people to go there. There is a stair way to hell from the Maru royal palace, elevators to hell from both Dreamland Castle and Alva's penthouse, and the volcano on Mermaid Island connects to Hell. However, souls cannot leave Hell unless they are contained in a bottle, and they must reunite with their bodies on Earth should they leave hell and wish to stay there.
According to Luci, most writers end up in Hell, possibly because they are alcoholics. He also claimed that they feed lemons to children in Hell, and that they have only one genre of theater productions, which are the same kind of interactive plays performed in the Dankmire Children's Theatre. When Bean read the Book of the Dead, she notices there was a surprising high amount of Popes in there.
Hell likely has schooling and education, as Luci was a communications major and he always wanted to be in the entertainment business, meaning he probably had the opportunity.
Souls send to hell are tortured in various ways, but the most common torture seems to be that these souls are chained to a wall or chair and forced to watch the worst moment of their lives over and over on a television:
- Hansel and Gretel were forced to watch the moment Bean killed them.
- Elfo had to watch the moment that Bean choose to revive Queen Dagmar with the Eternity Pendant instead of him.
- Bean had to watch Elfo watching the abovementioned scene, and his sadness as he realized his friend could have revived him but did not.
