Mantic has a new army list up on their website for Kings of War 2nd edition. This time around it's the Twilight Kin.
Yeah, I wasn't exactly thrilled with the name of the army, either. It's their evil elves faction. Do they sparkle in the sunlight? Perhaps. You could use some iridescent paint on them.
You can get the rules for free over on the Mantic website. However, these are beta-versions of the rules. So things may still change. Mantic has a big overhaul of the army and the background for the faction. So be on the lookout for that.
