In-game description
"Storm clouds gather in the North. There are rumours that the barbarous tribes residing in the shadow of Chaos have ceased striving against each other for the attention of the Dark Gods and are instead banding together. Suckling at the teat of Chaos, the hordes grow in strength. It seems only a matter of time before the dam breaks and a tide of ruin bursts forth to engulf the Old World, corrupting or destroying all in its path.""Marshal your strength, nurture the sinews of war, build your walls high, gather warriors to your banner and temper them in the crucible of battle, so that when the time comes you may yet weather the storm!"
