The God of War, Feiyana, possessed two Semi-Divine Artifacts: the Upper Class Semi-Divine Artifact of Natural Fury and the Middle-grade Semi-Divine Artifact Commander's Sword.
The former came to be when Feiyana, then the Legion Commander, lent her own Middle-grade Semi-Divine Artifact to Copperbeard Furnace of the Dwarf Heroic Clan for him to observe and comprehend.
In return for this opportunity, Copperbeard Furnace of the Dwarf Heroic Clan successfully grasped deeper techniques for crafting Middle-grade Semi-Divine Artifacts and also developed a concept for how to forge an Upper Class Semi-Divine Artifact.
Afterward, Copperbeard Furnace of the Dwarf Heroic Clan successfully mastered the techniques for forging Upper Class Semi-Divine Artifacts. He then upgraded Natural Fury into an Upper Class Semi-Divine Artifact and returned it to Legion Commander Feiyana.
