Hell
Locations called Hell existed in several universes. They could be a location within a wider universe, a pocket dimension in sync with a more mundane universe, or a universe all of their own.
Nature
Hell was generally a place of evil and suffering, populated by Demons and ruled over by the Devil. It was a place of eternal punishment, or at the very least imprisonment, for the damned, souls who had once been living mortals and had been found unforgivably corrupt upon death. It was occasionally possible for a living person to be physically, forcibly dragged to Hell. (COMIC: Jenny Everywhere Vs Hell)
History
Conquered by Jenny Everywhere
One universe's Hell was accessed from a gate located in a limbo area, which led into a descending spiral staircase. The damned would be tried by one of at least six robotic demon judges for their “sins” (as defined by a rather antiquated divine plan which included things like “Not making any of the correct animal sacrifices” as damnable offences, not to mention such things as homosexuality).
For unclear reasons, the local incarnation of Jenny Everywhere was once snatched from her bed and pulled into Hell. She was condemned to “having a goat stuck to her head”; as the demon showing her around reluctantly admitted, the demons had run out of good ideas for ironic punishments around 1993, and were now making them up at random. Rejecting the punishment, Jenny escaped her captors and then faced the Devil.
Drawing on the mental fortitude granted to her by her multiversal nature, Jenny overthrew the Devil and declared this to be “Day One of the Republic of Hell”, proposing to organise the damned and other wayward souls into some kind of off-kilter utopia. (COMIC: Jenny Everywhere Vs Hell)
Behind the scenes
Hell, one of the notorious recurring elements in real-world human beliefs about the Afterlife, can be considered a public-domain concept in its own right.
