hobilendurite
Hobilendurite is a theoretical mineral hypothesized to exist within the complex geological formations of the planet Xylos. Discovered through deep-space spectroscopic analysis, its unique spectral signature suggests a composition rich in silicates and an unusual metallic element, provisionally named "xylosium." Preliminary models indicate that hobilendurite forms under extreme pressure and temperature conditions found deep within Xylos's mantle, possibly near the boundary with its core.
The hypothetical mineral's crystalline structure is predicted to be highly ordered, contributing to its theoretical density
