Of course, the difference lies in order of power-while many D&D adventures focus on allowing a band of heroes to prevail over a Dark Lord (much as in the spirit of Bram Stoker's novel Dracula), no such victory over the Dark Powers is conceivable. Where the players are often tormented and opposed by the Dark Lords, the Dark Lords are themselves tormented and opposed by the Dark Powers. The Dark Powers most frequently serve as a plot device for Ravenloft, especially concerning the Dark Lords, the de facto visible rulers of the Ravenloft Demiplane. Their exact nature and number are deliberately kept vague, allowing for plot development in accordance with the Gothic tradition of storytelling-where the heroes are frequently outclassed and outnumbered by unknowably evil forces beyond their control. The Dark Powers are a malevolent force who control the Demiplane of Dread. The phlogiston blocks all planar travel, but the mists can appear in deep space inside crystal shells, according to the Complete Spacefarer's Handbook. One exception is the 'phlogiston' of the Spelljammer setting. The magical mists of Ravenloft could appear anywhere in the Dungeons & Dragons universe, drawing evil-doers (or player characters) into the Ravenloft setting. Characters have a much greater significance attached to their acts, especially if they are morally impure, as they risk coming under the influence of the Dark Powers (through the game process called 'dark powers checks') and gradually transforming themselves into figures of evil. Dungeon Masters are encouraged to use scenes that build apprehension and fear, culminating in the eventual face-to-face meeting with the nameless evil. Ravenloft is primarily a Gothic horror setting.
