Realmsuch

Realmsuch is a neologism used in speculative fiction, world-building discourse, and some philosophical writing to denote the ontological character or "realness" of a realm within a larger system of multiple realities. The term combines realm with such, a shorthand intended to capture the texture, coherence, and distinctiveness that make a given realm feel concrete.

In usage, realmsuch refers to the properties that identify a realm beyond its surface details: governing laws, causal density, spatial-temporal structure, and the degree to which inhabitants and events appear principled rather than arbitrary. Proponents use realmsuch to compare realms, discuss narrative constraints, or justify mechanics such as travel rules, authority, or metaplot continuity.

Realmsuch is mostly found in informal discussions, fan wikis, and design guides rather than formal philosophy. Because it is a coined term, its precise meaning varies by author, with no standard metric. Some critics view it as a handy shorthand for world-building quality; others see it as redundant with existing concepts of ontological depth or coherence.

Related concepts include possible worlds, ontology, modal realism, world-building, and multiverse theory.
