The Prismatic Membrane manifested during the first catastrophic convergence of all ten realms, when a desperate wielder's need for protection crystallized into a living barrier of pure refracted light. Born from the collision between raw survival instinct and the Arcane Fracture's chaotic energies, it evolved beyond mere protection into a sophisticated interface for understanding dangerous magical phenomena.

This ethereal construct exists as a gossamer-thin barrier of crystallized light, its surface rippling with prismatic waves that automatically separate chaotic magical frequencies into distinct, manageable spectra. The membrane demonstrates remarkable responsiveness to magical threats, instantly adapting its refractive properties to neutralize harmful energies while allowing beneficial forces to pass through unimpeded. Its self-repairing nature ensures continuous protection even when subjected to the most volatile cross-realm magical collisions.

The Prismatic Membrane serves as both shield and analytical instrument, protecting wielders during dangerous cross-realm magical experiments while simultaneously revealing the hidden harmonic relationships between conflicting league energies. It functions as the essential interface that makes safe magical synthesis possible across all ten fractured domains.
