Forum:"Severing Soul" and "Thor's Wrath" in FE Awakening SpotPass?

I came across a person in the SpotPass that appeared on the map. They had a good, end game team but what confused me the most is that their Avatars (Their Original one and another they must have recruited) wielded a "Severing Soul" (With a Killing Edge icon) and a "Thor's Wrath" (With what looked like a Thoron or Mjolnir icon). I've looked everywhere on the internet and can't find these items.

Both items had a blue color to their names as if they were forged, so do Killing Edges and Thorons change their name when maxed out in forge? Or do you have to forge a certain way? I can't bring up this person anymore and it was just a person how apparently passed by. Please help.
