Hell

Hell was believed by some cultures to be the place of punishment after death for those who had sinned in life.

Concept
Hell was embedded in the minds of species like humans through religions like Christianity, the opposite afterlife being Heaven. The Seventh Doctor claimed there was no such place as Hell. (AUDIO: Gods and Monsters) The Twelfth Doctor claimed not to be scared of Hell as he believed it was "just Heaven for bad people". (TV: Heaven Sent)

Some people called the Void Hell. (TV: Army of Ghosts) Hell was also a part of Gallifreyan mythology. (AUDIO: Minuet in Hell)

The Third Doctor thought that the surface of an unnamed planet about to be destroyed by a supernova looked like the human conception of Hell. (COMIC: The Labyrinth)

In 1215, in England, the Fifth Doctor and his companions were mistaken as demons from Hell. (TV: The King's Demons)

Rita, a Muslim, believed that a Minotaur prison ship she was trapped in was Jahannam, the Islamic version of Hell. (TV: The God Complex)

Perception
Hell was often used to describe greatly uncomfortable situations. Morbius described his deteriorated state as hell, (TV: The Brain of Morbius) and the Tenth Doctor later described the Last Great Time War as hell. (TV: The End of Time)

Some associated Hell with the Devil. Winston Churchill once mentioned that "If Hitler invaded Hell, I would give a favourable reference to the Devil." (TV: Victory of the Daleks) Ian Chesterton said that a sandstorm sounded like "all the devils in Hell were laughing". (TV: "The Singing Sands")

The Twelfth Doctor wondered if the confession dial he was teleported inside was Hell. He thought Hell was just Heaven for bad people. (TV: Heaven Sent)

Real Hell
While it was a concept, Hell was also a plane of existence or universe somewhere in reality that had a fiery geometry. The Scourge lived here and tortured the humans of their universe. (AUDIO: The Shadow of the Scourge)

Jason Kane spent several years in Hell, described as predominantly rock where tunnelling craft tunnelled their way between bubbles of places which weren't rock, which would in theory be the equivalent of planets. (PROSE: The Infernal Nexus)
