Lightem

Lightem is a fictional concept that appears in speculative fiction, often within the context of futuristic or fantasy settings. It generally refers to a form of artificial illumination or energy source that possesses unique properties beyond those of conventional light. This can range from sentient light that can communicate or interact with its environment to a specialized energy field used for power or defense. The specific nature and function of lightem are typically defined by the author and the narrative in which it is presented, serving as a plot device or an element of world-building. In some instances, lightem might be a rare and valuable resource, while in others, it could be a common technology. Its exact characteristics, such as its spectrum, intensity, and behavioral patterns, are entirely dependent on the fictional context. The term itself suggests a play on words, combining "light" with a suffix that implies a manufactured or energized quality.
