Have you checked the PP bits store for jack swords? Maybe something from Menoth, or Gallant's sword (you can cut off the ribbons and fill in the fancy bits with greenstuff if you like)? A Stormclad sword, painted so it's NOT glowing, would fit the aesthetic at least. Oh, some Circle beasts have some swords too.
I checked to see if the Nomad's sword was available, but it was out of stock last night. If you're trying to keep it tournament legal, that's the only way besides finding someone who didn't magnetize it when building a Mule/Rover.
Are you a Wolf, a Sheep, or a Hound?
They called me crazy? They called me insane? THEY CALLED ME LOONEY!! and boy, were they right."
