Hell (also Gehenna, Hades, Hel, Jahannam, Sheol, Tartarus) is a fictional location, an infernal underworld utilized in titles published by DC Comics. It is the locational antithesis of the Silver City. The DC Comics location known as Hell is based heavily on its depiction in Abrahamic mythology. Aside from a brief appearance in DC Special Series #8 (1977) that was never referred to again, the DC Comics concept of Hell was first mentioned in Swamp Thing (vol. 2) #27 (July 1984), described by Alan Moore, and was first seen in Swamp Thing Annual #2 (January 1985), written by Moore and depicted by Steve Bissette and John Totleben.
