Fenni, Raskta
this woman was one of the best Echani duelists of her time, many years before the Great Sith War. Many types of bladed weapons were named or manufactured in her honor, including a foil that had cortosis woven into the steel of the blade. However, mass-production for use by other Echani warriors revealed that these foils were poorly manufactured, and many died with the cortosis didn't adequately deflect lightsaber attacks.
