Warhammer Fantasy Roleplay: Empire in Ruins

From publisher blurb:

After the events of The Horned Rat the heroes have won the respect and trust of many in Middenheim, but before they can capitalise on their renown the Empire descends into the turmoil of civil strife.A number of threats that the Characters may have thought far behind them reassert their influence. Icons of authority and leadership are found wanting, and the greatest nation in the Old World appears destined to shake itself to pieces.

Only by undertaking a dangerous journey can the Characters prevent the ruination of all they hold dear.
