This goddess is master of crystals. Those Duardin who worship Grêdnir primarily wear many crystals in their beards and on their armour. They enjoy shaping crystals and pray to this goddess before starting on a project. She survived into the Age of Sigmar, her commandments read as:
-Never knowingly produce an object that is less than the best you could make; to do so dishonours Grêdnir, the craft and yourself.
-Never make an object for any non-Duardin who has not first proved their worth and loyalty to the Duardin race.
-Work only with the best tools you can afford; your craft deserve the best.
