Lucent Catacombs

No one quite knows how they came to be, though most likely by mother nature's own doing in some way - a series of caverns spread out beneath the land. There are only three well known entrance points into the catacombs, yet despite the looming darkness and shadows a slight dim glow seems to sparkle off it's dirt encrusted walls. A series of crystals and diamons fauceted into the soil reflecting light in a wide array can provide one with the means to see better. Though be careful you don't wander too far, sometimes a branch of the catacombs will collapse and due to it's large size one might find themselves lost within it's unfathoming depths.
