Expansion - Crusader Kings II: The Reaper's Due

DLC

The Reaper’s Due adds a host of new mechanics centered on the Black Death and other world shaping epidemics. Lock your gates to keep the plague from infecting your court, even if it means cutting yourself off from your suffering citizens. Peace and good management will see your provinces reward you with greater wealth and manpower, but constant war and disease may depopulate your countryside.
