From the "Legion: Warrior Artifact Review" official blog: In ages past, the titanic watcher Keeper Odyn betrayed the sorceress Helya, killing her and twisted her spirit into a spectral Val'kyr. He forged this pair of swords for the mightiest of his storm-forged Valarjar, but Helya stole the swords and infused them with a portion of her rage. She then gave them to her own champion, who used them to hunt the greatest of heroes and drag their souls away to serve in Helheim.
