Yes there was and somewhere on the net there still is. My group explored it from late October to, like, March this year. Great fun.
As for the related warbands there was a revised edition of them out there before the Big Change in GWs site. I can't find my printed copies at the moment and of course I lost the links when I switched computers...
I also recommend the Nemesis Hired Swords for an Empire in Flames setting.
We'll see on the 7th King!
Go Blue!
Bye the bye you wouldn't be participating in the Crisis in Marienburg campaign would ya?
Long live the Emperor of Middenland!
