Well, a few days ago I started with a Warhammer novel, it mostly deals the Von Carstein legacy that I have read so far, and there was one particular page that got me angered. It was early in the book, it was in the first 5 pages of the book! The one individual is doing some everyday Warhammer scrying in a pool of blood. Seeing what happens with the rise of Nagash, how everything is crumbling, dying and pretty much ending. So he looked into the bloody pool and saw a race of reptilian humanoids, fighting a massive battle in Lustria against the demons and actually winning. Afterwards there is a mist that comes through the temple cities and as it passes it turns our beloved lizardmen in disfigured monsters. Now by your guess would that mean if all of Lustria was destroyed, does that mean there are no Lizards left, or are there still some hope in the South Lands? Or will the lizards survive this mess?
that is being very much speculated on right now, heavily. No one knows. If you read into the "end time rumours", you will be as updated as the rest of us.
