Interrealm

Interrealm is a term used to describe interaction, travel, or communication between different realms, planes, or dimensions. In fiction, it refers to the crossing of boundaries that separate distinct worlds, often facilitated by portals, gateways, magical rites, or advanced technology. The word combines the prefix inter- meaning between with realm, a term for a distinct domain of existence.

Etymology and scope: The compound is English in origin and widely used in fantasy and speculative fiction. It is not tied to a single canon but rather functions as a generic concept for multirealm narratives, parallel-world plots, and metafictional discussions of reality.

Mechanisms: Common vehicles include portals, rifts, celestial doors, or items with inter-realm properties. Travel can be instantaneous or require preparation, safety protocols, or alignment of cosmic forces. Rules for interrealm travel are often defined by the work's internal logic, including consequences for crossing boundaries, such as disruptions to time, memory, or identity.

In culture: The concept appears across literature, games, film, and theory, serving to explore themes of otherness, sovereignty of realms, and the fragility of reality. It often carries implications for governance, diplomacy, and conflict when multiple realms interact.
