Hell while Lucifer roamed Earth and owned a piano bar named Lux (the Latin word for "light") as depicted in the ninth Sandman story arc, The Kindly Ones, in Vertigo Jam #1 (August 1993) and The Sandman (vol. 2) #57–69 (February 1994–July 1995). The six-issue miniseries Human Defense Corps (July–December 2003) detailed the U.S. military designation for demons as "Hostile Species NHH-014". The Human Defense Corps were able to defeat a minor Lord of the Damned named Scarmaglione, then Sergeant Montgomery Kelly of the Corps killed him, assumed his powers and claimed his clan for the United States of America. His status as a minor ruler of Hell was confirmed by no less an authority than Neron himself, who was still the ruler of Hell at that time. Superman briefly became the Lord of Hell in Superman #666 (October 2007). The eight-issue miniseries Reign in Hell, also including DC Universe Special: Reign in Hell #1 and created by Keith Giffen and Tom Derenick, introduced a new status quo for the mainstream DC Comics version of Hell; it also gave readers specific geographical references of the region and defined a codex of rules that governed the damned (however, it is also known to have had many internal continuity errors that make its place in mainstream DC Universe canon questionable at best). Two years after Reign in Hell, DC Comics decided to remove all DC Universe characters from their Vertigo imprint, though Vertigo would have its own version of John Constantine the Hellblazer for a time. DC Comics Description In the mainstream DC Universe, Hell is an alternate plane of reality, traditionally accessible only by those with demonic heritage, beings of a higher order, and those whose souls have been barred from entering the Silver City because of any evil that they had committed in their lives. DC Comics' Hell is a debased reflection of Earth, meaning that as Earth became more technologically or socially advanced so did Hell, due to an effect not unlike time dilation: "[a] day in Hell is equal to a minute's passage on Earth". All denizens of the mainstream DC Comics version of Hell are capable of using some form of maleficium; the most powerful infernal magic users are the ruling gentry of Hell and their enforcers the Necro-Mages, Forges, Exegesis Guild, Renderers, Howlers, Incendiaries, Rhyming Demons and Wishweavers.
