Mundane Crystals and their sources:
Mhanna is a special energy that exists in all things on Mharik, especially so in a mineral called Mundane Crystal. MC, unlike other minerals, can only be found in monsters. Depending on the monster they are taken from, the crystals properties usually resemble the element and/or strength of life in the monster. The inhabitants of Mharik use these crystals to power lights and primitive heavy machinery. Some smaller more condensed MCs are used in weapons. Shards are used as ammo for launchers *big primitive gunpowder rifles* These shards have special properties, fire, ice, explosive, super hard etc etc. Larger crystals are used for powering machinery, small crystals *not shards* are used to augment weapons and armor. Monster parts are useful for armors and weapons. Augmenting MCs are placed and removed from slots embedded in armors and weapons. The quality of a crystal effects it's strength when used. Also, really rare types are said to actually fuse with the items they are embedded into, granting great power to it but causing it to reject any other type of crystal. Using two of the same quality and type generates a stronger effect.
