When the Great War was over, the gods have tasked the elementals to protect the objects that contain the essences of power. The Earth Elementals are the protectors of the lucky gems. The Fire Elementals are the stewards of the god's blessings. The Water Elementals are the guardians of the soul stones. The Air Elementals are the defenders of the dragonshards.
