Xliiteline
Xliiteline is a fictional mineral used in speculative fiction and worldbuilding. In published and fan-created works, it is described as a dense, anisotropic crystalline material with a characteristic blue-green luminescence and a layered, silicate-like or carbide-like structure. There is no single canonical formula, and depictions vary between authors and settings.
Properties commonly attributed to Xliiteline include a very high refractive index and a strong nonlinear optical
Formation and occurrence are equally variable. In many stories, Xliiteline is said to form under extreme pressures
Applications in fiction range from high-capacity photonic chips to energy-dense storage lattices and novel sensors. Cultural
Note: Xliiteline does not exist outside of fictional worlds and has no real-world scientific basis. Citations
