Techno fantasy locations often take the form of a literal "above and below," where the shining palaces of the wealthy steal the very sun from the vast majority of the people who struggle daily in the slums below. Outside the cities lies a barren world drained of all life and beauty, turned grey by human greed.
In a techno fantasy world, magic has largely been claimed by technology and turned into yet another source of power, wealth, and warfare supremacy. The stream of souls has been gravely wounded and corrupted, and the original ways of magic were forgotten or — more likely — suppressed.
The antagonists of a techno fantasy world should represent the darkness of modern society and the ruthlessness of industry and exploitation. Wealthy and influential, they simultaneously base their authority on brute military force and stolen magic or artifacts. But perhaps their most insidious quality is that many people still see them as ideal leaders and miraculously self-made saviors, and are willing to be exploited and oppressed every day in the vain hope of gaining their favor. Left unchecked, their egotistical ambitions will lead to magical cataclysms or full-scale war.
