For the Delta Quadrant planet or Paramount Studios set, please see Planet Hell.
Hell was the underworld in some ancientHumanreligions, typically ruled by a figure called the Devil. It was believed people would be sent here after their death, if they did not adhere to the religion's code.
Hell was referenced in the final draft and the revised final draft of the script for TOS: "The Enemy Within", which described space as "heaven for some... hell for others...."
In an underlined sentence from a memo Gene Roddenberry wrote D.C. Fontana about her first draft script of TOS: "Charlie X" (the memo was dated 13 June1966), Roddenberry emphatically advised that, owing to the influence of Charlie Evans, the USS Enterprise "should become a hell ship!" Hell was consequently referenced in the episode's final draft script, with Captain Kirk warning Spock and DoctorMcCoy that, due to Charlie's presence on the vessel, the Enterprise might become "a hell ship," to which McCoy, considering that Evans had already begun to have substantial destructive influence on the ship, rhetorically asked, "Isn't that what we've got now?"
