"When cataclysm loomed over the Near East, the hero Mirza arose to defend the people from fell fiends. Once he had torn the monsters apart, he raised a mighty empire- and fashioned a pair of weapons such as these from his foes' claws!" - Jalzahn

In retrospect this makes me think of the Final Days of Thavnair, especially since the weapons have a very carpace-y/alien appearance that's consistent with the aesthetics of Blasphemies. Obviously the cataclysm in question isn't the final days but it makes me wonder if we have any other info on the "fell fiends" or Mirza?
