Planeve

Planeve is a fictional construct used in speculative fiction to describe a transitional subdimension that connects a base plane with higher-dimensional spaces. The term is a portmanteau of plane and veil, signaling its role as a veil that can be pierced to access adjacent realms.

Definition and characteristics: In proposed uses, a planeve is modeled as a two-dimensional manifold embedded in a higher-dimensional ambient space. Locally it follows ordinary planar geometry, but globally it can curve, twist, or thread through extra dimensions. Planeves may support fields or interactions that are not permitted on a simple plane, such as selective energy transmission or direction-dependent permeability. Access to a planeve is typically described as requiring a specific artifact, alignment, or ritual within the fiction.

Origins and usage: The concept has appeared in several works of speculative fiction and in fan worldbuilding resources. It functions as a narrative device to explain unusual portals, teleportation phenomena, or cross-dimensional interfaces without invoking full higher-dimensional machinery.

Theoretical framing: In-world explanations range from magical to quasi-scientific. Critics and readers often treat planeves as metaphorical tools to discuss boundaries, perception, and dimensionality, rather than as established physical entities. Some writers emphasize its mathematical flavor by describing planeves with constraints that resemble planar surfaces embedded in a richer geometry.
