This makes me sooooooo happy to be seeing 3rd party Tau Empire models. I'll need to save up a couple of bucks since these aren't exactly cheap, but they will be mine eventually. I'm not completely sold on all the sculpts, but it'll be super nice to have something unique but that perfectly fits the aesthetic.
These come from the good folks at WargameExclusive.com.
I'm guessing the pistol models would be good Pathfinders. The sword model would be a good counts-as Ethereal. The last is obviously a Fire Warrior or Fireblade. It's hard to tell, but she's holding an Inquisition necklace.
