The Name of the Rose
The steady stream of crystals from this place supported the energy consumption of the entire Sear Empire.
There were many types of crystals. Some could be made into expensive ornaments and jewelry, while others were worthless. Another type, which naturally stored energy, could be used for lighting and heating. However, the quality of such crystals varied greatly. Unstable ones were prone to exploding, while those from high-quality veins were expensive and usually reserved for the upper-class nobility and wealthy households. Inferior crystals were mostly used by commoners, while the poorest at the bottom could only use the most primitive oil lamps and firewood.
