Realms are distinct areas or domains that can refer to various contexts, such as fantasy literature, gaming, or even metaphysical concepts. In fantasy settings, realms often represent different worlds or dimensions, each with its own unique characteristics, inhabitants, and rules. For example, in the Dungeons & Dragons universe, realms can include magical lands inhabited by various creatures. In a broader sense, realms can also refer to fields of knowledge or influence, such as the political realm or the realm of science. These realms help categorize and organize different aspects of human experience, making it easier to understand complex systems and interactions within society.
