Winged Lancers coming to a Fantasy Battlefield near you soon - right now actually - duck !
This army is completely unofficial and is not endorsed by Games Workshop!
A quick review of the book reveals some very nice presentation changes with a superb new Russian style font, the ones with the "backward" R's (where he finds them, I know not !)
There is quite a bit of new artwork and a few army unit changes including new Lord and Hero level special characters (such as Miska the Slaughterer and Igor the Terrible) and some interesting sounding new units including the Kvassnics, Chekist, Armoured War Bear, Brotherhood of the Bear, Droyaska skirmishers and a new Lore of the Hags.
I haven't had time to give the book a decent read, only skimming through it, so I will leave that to you folks (click the book cover).
I have both pdfs open side-by-side and the new one certainly has more of the Icy Wastes feel to it. Hopefully one day, I will actually get time to not just read but use one of these armies on the field of battle !
Mathias asked me to tell you that most of the background is from Realm of the Ice Queen (and the original list was written by Tuomas Pirinen) and not written by Mathias.
