The Empire is the largest realm of Men in the Warhammer world. The Emperor's powerful armies form the bastion that keeps the marauding Orcs and forces of Chaos from overrunning the Old World.

"I can see in your eyes that you fear this enemy. I can see in your eyes that you wonder how we can fight such terrible monsters. Men of the Empire, I have the answer: We fight them with our steel, we fight them with our courage, but above all we fight them with our faith in Sigmar."
