Reign in Hell (comics)
Reign in Hell is a 2008-2009 comic book miniseries written by Keith Giffen, pencilled by Thomas Derenick, inked by Bill Sienkiewicz and published by DC Comics. The title is a reference to a line spoken by Lucifer in John Milton's epic poem Paradise Lost: "Better to reign in Hell than serve in Heaven".
Plot
Hell is thrown into a massive conflict as Neron and his generals are confronted with a rebellion led by Blaze and Satanus, the rulers of Purgatory. Neron soon discovered that the rebel demons were offering the damned "hope to the hopeless" and redemption for them. Realizing what would happen if the damned ever rose up against him, Neron has his consort Lilith, the mother of all Earthborn fiends, summon all of the vampires, werewolves, ghouls and infernally powered humans to Hell to fight on his side.This unrest soon attracts the attention of Earth's magical superheroes, who are concerned about the outcome and the possible repercussions of the war. Many of them descend into Hell and take sides in the conflict, including Giovanni "John" Zatara, his daughter Zatanna Zatara, Jason Blood a.k.a. Etrigan the Demon, Randu Singh, Doctor Fate V, the Ragman III, the Creeper, Detective Chimp, the vampire Lord Andrew Bennett, Acheron, the angel Zauriel, the Enchantress, Deadman, the Phantom Stranger, Sargon the Sorcerer II, Ibis the Invincible II, the Nightmaster, Nightshade II, the Midnight Rider, the Warlock's Daughter, Black Alice, Blue Devil, Red Devil and the fallen angel Linda Danvers. Doctor Richard Occult, aided by the Yellow Peri, also descends into Hell, but separately from the others and with his own ulterior motive-to free the soul of his beloved, Rose Psychic, from damnation.
Lobo, who at this time is confined to the Labyrinth, Hell's only prison and whose suffering alone is enough to power Neron's entire palace, is freed from his torment as a result of the titanic battle between Etrigan and Blue Devil. Lobo then tears apart the soul of Zatara, which forces Zatanna to destroy his soul and banish it to the Abyss at his request, rather than to consign him to an eternity of pain and torment.
Just when Neron seems to be victorious, Satanus finally reveals that he used the war as a cover in order to spread a modified viral version of DMN, the anagogic drug that changes humans into monsters and that he had used once before in order to destabilize Metropolis and confound Superman. This variation of DMN is airborne and, when combined with the speaking of the magic word "Shazam", it transforms Neron and all of Hell's demons into soulless humans except for Lilith, who was not a true demon. This causes all of the demonic entities that Neron has consumed over the millennia to be cast out of him. Satanus then beheads Neron and takes the throne of Hell for himself. The damned then turn their rage upon the now-human and powerless demons, slaughtering them and damning themselves anew.
Blaze later takes advantage of her brother's momentary weakness during a moment when he allows Black Alice to touch him and sample his powers; this action shatters Black Alice's psyche and allows Blaze to drain Satanus' power and take the throne for herself, thus winning the war. Near the end of the miniseries, the Unspoken Principium of Hell is revealed by Doctor Occult to be "You can leave whenever you want".
