The term describes entities, objects, or locations originating from or existing within a plane of existence beyond the prime material plane. These other planes are often governed by different physical laws and may host unique creatures and environments. As an example, a celestial being hailing from a realm of pure light, or an artifact forged in the fiery depths of an infernal domain, would be considered to have this characteristic.
Understanding origins beyond the material world is crucial for comprehending powerful entities and artifacts. It provides context for their abilities, motivations, and potential impact on the known world. Historically, interactions with sources from these realms have often been pivotal moments in shaping civilizations, leading to both advancements and cataclysmic events.
