The Crystal Labyrinth

The Crystal Labyrinth is a system of glowing caverns that stretches beneath the Sierra Nevada mountain range.


The Crystal Labyrinth was discovered by a group of surveyors in 1987. They named this site for its many branching tunnels, and the crystalline M42 the can be found marbled throughout the walls of the caverns. The entrance of the Crystal Labyrinth was found under the ruins of a large structure of unknown origin, which has been named El Castillo de Vidrio. In 1993, a research station was established near the Castillo, and research of the Castillo and the Labyrinth has been ongoing ever since.


The Crystal Labyrinth is made up of many interconnected caverns. Currently, these caverns have not yet been fully explored by researchers. Therefore, the Labyrinth’s full extent is unknown at this time.

The walls of the Crystal Labyrinth consist primarily of granite and obsidian. Throughout the Labyrinth, the walls are veined with a crystalline substance, which is completely made up of a previously unidentified element. Researchers have labeled this element M42, since its various colors and glow was similar to images of the Orion Nebula. This substance continually gives off a faint glow, which appears to be independent of any outside light sources or detectable radioactivity. M42 does not consistently glow a single color, instead giving off a multi-colored, prismatic effect. The glow given off by the M42 in the walls of the Crystal Labyrinth gives its tunnels their signature glowing appearance.
